You also observe a giraffe running in a straight line. You clock her and find that she goes from rest to her top speed of 26.82 m/s in 3 seconds. You also observe that she can only run for 38 seconds before tiring to the point that she needs to stop. What is the velocity of the giraffe when she gets tired?

A student at the top of a building of height h throws one ball upward with a speed of vi and then throws a second ball downward with the same initial speed vi. Just before it reaches the ground, is the final speed of the ball thrown upward (a) larger, (b) smaller, or (c) the same in magnitude, compared with the final speed of the ball thrown downward?
A car is traveling on a straight, level road under wintry conditions. Seeing a patch of ice ahead of her, the driver of the car slams on her brakes and skids on dry pavement for 70 m, decelerating at 6.0 m/s2. Then she hits the icy patch and skids again. The car takes a duration of 85.0 s to come to rest during the second skid. If her initial speed was 50 m/s, what was the magnitude of the deceleration on the ice during the second skid. 1. Which of the following kinematic equations would you use to determine the velocity of the car after skidding on the dry pavement for 70 m? 2. Determine the velocity of the car after skidding on the dry pavement for 70 m. 3. Which of the following kinematic equations would you use to determine the deceleration of the car after skidding to a stop on the icy patch? 4. Determine the magnitude of the deceleration of the car after skidding to a stop on the icy patch.

A rock, released at rest from the top of a tower, hits the ground after 1.5 s. What is the speed of the rock as it hits the ground? ( g = 9.8 m/s 2 and air resistance is negligible)
a cheetah and a gazelle are both stopped. The gazelle runs and accelerates so that it reaches a velocity of 20 m/s after 100m, then runs at a constant velocity of 20 m/s. The cheetah waits 3 seconds and accelerates at 2.5 m/s to reach a final velocity of 22 m/s and then travels down the road at 22 m/s. When does the cheetah catch the gazelle? How far do they travel?
A test rocket is fired vertically upward from a well. A catapult gives it initial speed 60 m/s at ground level. Its engines then fire and it accelerates upward at 5.0 m/s² until it reaches an altitude of 1,100 m. At that point its engines fail and the rocket goes into free-fall, with an acceleration of g=9.80 m/s². What is its velocity just before it collides with the Earth? (You will need to consider the motion while the engine is operating separately from the free-fall motion.) [Give your answer in m/s to the nearest 0.1 m/s]
A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 58.8 m/s in 6 seconds. She then pulls the parachute cord and after a 4 second deceleration, descends at 10 m/s for 60 seconds. reaching the ground. From what height did the parachutist jump?
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?
Julie, who has a mass of 65 kg, is enjoying a day at the local water park with some friends. She waits for her turn at the top of a water slide and then begins sliding down. The topof the water slide is 12 m above the pool and the bottom is 1 m above the pool. How fast is she moving when she reaches the bottom, in m/s? (Round your answer to one decimal place if necessary.)
A roller-coaster goes over an 14 m tall hill then approaches a 25 m hill. What is the minimum velocity the roller-coaster would need when going over the 14 m hill to make it to the top of the 25 m hill?
Hi there! I am not exactly sure how this website works, however, here is a question I could use some guidane with. Rosana takes her puppy for a walk, but they can't stray too far from home or the puppy gets nervous! They walk 342 m south, then 579 m north, all in a time of 12.3 minutes. What is their speed? Thanks!
A pilot ejects from his aircraft and falls 80 m from the ground without friction. Whenhe opens his parachute, he decelerates at 3.5 m/s2. The pilot hits the ground at 5 m/s.How long was the pilot in the air and at what height did he begin his fall?
