An initially motionless test car is accelerated uniformly to 120 km/h in 8.13 s before striking a simulated deer. The car is in contact with the faux fawn for 0.695 s, after which the car is measured to be traveling at 65.5 km/h. What was the magnitude abefore of the acceleration of the car before the collision? What is the magnitude davg.col of the average acceleration of the car during the collision? What is the magnitude of the average acceleration aavg,test of the car during the entire test, from when the car first begins moving until the collision is over? abefore = davg.col = davg.test = m/s² m/s² m/s²
MY NOTES ASK YOUR TEACHER A cab driver heads south with a steady speed of v, -20.0 m/s for t-3.00 min, then makes a right turn and travels at v₂ - 25.0 m/s for fy 2.20 min, and then drives northwest at v₂ - 30.0 m/s for ty-1.00 min. For this 6.20-min trip, calculate the following. Assume +x is in the eastward direction. (a) total vector displacement (Enter the magnitude in m and the direction in degrees south of west.) Im magnitude direction (b) average speed (in m/s) m/s south of west (c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) magnitude: direction m/s south of west
The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? i have tried so many ways to solve this and i cant please explain
In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of 183.58 mi/h. The one‐way course was 5.00 mi long. Acceleration rates are often described by the time it takes to reach 60.0 mi/h from rest. If this time was 4.00 s, and Burt accelerated at this rate until he reached his maximum speed, a. how long did it take Burt to complete the course? b. Sketch position vs time, velocity vs. time, and acceleration vs. time graphs for the race.
12. Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 t%s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 /32. It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 151/,2. Determine the minimum distance d be tween the cars so as to avoid a collision. (Practice at Home) A B

A student begins at rest and then walks north at a speed of v1=0.65m/s. The student then turns south and walks at a speed of v2=0.28m/s. Take north to be the positive direction. a)What is the student's overall average velocity vavg, in meters per second, for the full trip assuming the student spent equal times at speeds v1 and v2? b) If the student travels in the stated directions for 30.0s30.0s at speed v1 and 20.0s at speed v2, what is the net displacement, in meters, during the trip? c) If it takes the student 1.2s to reach the speed v1, from rest, what is the magnitude, in meters per squared second, of the student’s average acceleration during that time?
Osama was testing his new car by racing with his fiend Adam, Osama was driving at 54.0 mile/hr, enters a one-way narrow subway. Osama then observed a Truck 100 m ahead traveling at a low constant speed 3.00 m/s. Osama used his brakes but can accelerate only at -2.00 m/s2 because the road was wet. Will there be an accident? Explain. If yes,Page 5 of 85at what time the accident occurs and how far into the subway. If no, determine the distance of closest approach between Osama’s car and the Truck. (1mile=1609m).
