6: In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small.

In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life- threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. If we assume that a pilot's speed upon impact was 123 mph (54 m/s), then what was his deceleration? Assume that the trees and snow stopped him over a distance of 3.0 m.
A tortoise and a hare are in a road race to defend the honor of their breed. The tortoise crawls the entire 1000 meters at a speed of 0.2 m/s. The rabbit runs the first 200 meters at 2 m/s, stops to take a nap for 1.3 hours, and awakens to finish the last 800 meters with an average speed of 3 m/s. Who wins the race and by how much time?
I need help with this problem A student in Physics 211 decides to do an experiment. They travel to a city and climb to the roof of a building that is 3.0 x 102 m tall. Then, at the same instant, they drop one rock while a second rock is thrown downward with an initial speed of 16 m/s. Assume both rocks experience negligible air resistance while falling. How much EARLIER does the thrown rock strike the ground? A) 1.1 s B) 1.5 s C) 1.4 s D) they land exactly at the same time
Suppose you take a 3-hour trip in your car. For the first hour, you travel at a speed of 60 mi/hr. The weather suddenly gets very bad so that for the remaining 2 hours you travel at a speed of only 30 mi/hr. What was your average speed for the full three-hour trip? I
1. A dog runs back and forth between its two owners, who are walking toward one another (Figure below). The dog starts running when the owners are 10.0 m apart with a speed of 3.0 m/s. (a) If the owners each walk with a speed of 1.3 m/s, how far has the dog traveled when the owners meet? (b) If one owner walks with a speed of 1.6 m/s while the other walks at 1.3 m/s, what is the total distance traveled by the dog when the owners meet? 13 m/s 30 m/s -100 m- 13 m/s
Cliff height. You are climbing in the high Sierra where you suddenly find yourself at the edge of a fog-shrouded cliff. To find the height of this cliff, you drop a rock from the top and 10 s later hear the sound of it hitting the ground at the foot of the cliff. Ignoring air resistance, how high is the cliff if the speed of the sound is 330 m/s?
Peacock mantis shrimps (Odontodactylus scyllarus) feed largely on snails. They shatter the shells of their prey by delivering a sharp blow with their front legs, which have been observed to reach a peak speed of 23 m/s. What is this speed in kilometers per hour?
Cheetahs have the highest top speed of any land animal, but they usually fail in their attempts to catch their prey because their endurance is limited. They can maintain their maximum speed of 30 m/s for only about 15 s before they need to stop.Thomson’s gazelles, their preferred prey, have a lower top speed than cheetahs, but they can maintain this speed for a few minutes. When a cheetah goes after a gazelle, success or failure is a simple matter of kinematics: Is the cheetah’s high speed enough to allow it to reach its prey before the cheetah runs out of steam?The following problem uses realistic data for such a chase.A cheetah has spotted a gazelle. The cheetah leaps into action, reaching its top speed of 30 m/s in a few seconds. At this instant, the gazelle, 160 m from the running cheetah, notices the danger and heads directly away. The gazelle accelerates at 4.5 m/s2 for 6.0 s, then continues running at a constant speed. After reaching its maximum speed, the cheetah can continue…
Question 3. Siblings Alice and Bob saved their money all summer to buy a water balloon launcher, and they are eager to take it for a test run. Younger brother Bob thinks he's a pretty fast runner with a top speed of 5 m/s. Не poses the following challenge to his sister: "I'll stand 20 m from you and I'll start running away as soon as you launch a water balloon. See if you can hit me!" Unfortunately for Bob, Alice is a physics 8A ace and knows exactly what needs to be done to soak her brother. (a) Set the origin of your coordinate system at Alice's position with Bob starting along the positive x-axis (and running along the x-axis). Assuming Bob runs at a constant velocity, what is Bob's trajectory rB(t)? (b) Suppose the water balloon launcher is limited to only firing at an angle of T/4. In terms of the unknown initial launch speed v, what is the trajectory of the water balloon rwB(t)? (c) What speed v should Alice launch with to ensure a direct hit? (d) How long does the balloon take…
1) A train is travelling at 60km/h when Superman slams head-on into it bringing it smoothly to a stop before it falls off a cliff. Superman is able to stop the train in an amazing 2.5 seconds! what is the acceleration of the train? how many g's did the people on the train pull during this stop? (hint: 1g = 9.8m/s^2) 2)you are about to skateboard down a long hill. Your initial velocity is 2.0 m/s south. When you reach the bottom of the hill you are travelling at 6.0 m/s south. It took 57 seconds to reach the bottom of the hill. What was your displacement?
1. Falls resulting in hip fractures are a major cause of injury and even death to the elderly. Typically, the hip's speed at impact is about 2.0m/s. If this can be reduced to 1.3m/s or less, the hip will usually not fracture. One way to do this is by wearing elastic hip pads. (a) If a typical pad is 5.0 cm thick and compresses by 2.0 cm during the impact of a fall, what constant acceleration (in m/s²) does the hip undergo to reduce its speed from 2.0 m s to 1.3m/s (b) The acceleration you found in part (a) may seem rather large, but to assess its effects on the hip fully, calculate how long it lasts. Note: convert cm to m first.
Fast Car: On a hot day in the flats, the temperature is 103.6 degrees. A driver finds an empty, flat stretch of desert that is 1776 meters long and decides to push the limits of his car. He finds the car can accelerate from 0 to 60 mph (26.8 m/s) in 4.30 s. Now he wants to see how fast the car can go. Assume the car maintains the same average acceleration until it reaches its top speed of 84.8 m/s. (a) How long will it take the car to reach its top speed? (b) How far will the car travel before it reaches its top speed?
