An initially motionless test car is accelerated uniformly to 115 km/h in 8.23 seconds before striking a simulated deer. The car is in contact with the faux fawn for 0.575 seconds, after which the car is measured to be traveling at 87.5 km/h. Answers must be to the correct number of sig figs. a) What is the magnitude of the acceleration of the car before the collision? b) What is the magnitude of the average acceleration of the car during...

An initially motionless test car is accelerated uniformly to 105 km/h in 8.03 seconds before striking a simulated deer. The car is in contact with the faux fawn for 0.455 seconds, after which the car is measured to be traveling at 87.5 km/h. What is the magnitude of the acceleration of the car before the collision? Number m/s What is the magnitude of the average acceleration of the car during the collision? Number m/s What is the magnitude of the...

In a crash test, a car with a mass of 1600 kg is initially moving at a speed of 18 m/s just before it collides with a barrier. The final speed of the car after the collision is zero. The original length of the car is 3.80 m , but after the collision, the smashed car is only 3.23 m long Part 1: What is the average speed of the car during the period from first contact with the barrier...

In a crash test, a car with a mass of 1500 kg is initially moving at a speed of 18 m/s just before it collides with a barrier. The final speed of the car after the collision is zero. The original length of the car is 4.48 m, but after the collision, the smashed car is only 3.86 m long. Making the very rough approximation that the large force that the barrier exerts on the car is approximately constant during...

A 1300-kg car, initially at rest, is initially accelerated at 4.9m/s2. After the car moves 550m, the engine is cut off. The car then moves a distance of 1230 before coming to a stop. Assume the road to be level and that g = 10 N/kg. a) What is in m/s, the magnitude of the velocity of the car at the end of the first 550m? b) What is in m/s2, the magnitude of the acceleration of the car while...

Use the exact values you enter to make later calculations. A uniformly accelerated car passes three equally spaced traffic signs. The signs are separated by a distance d = 21 m. The car passes the first sign at t = 1.3 s, the second sign at t = 3.7 s, and the third sign at t = 5.5 s. (a) What is the magnitude of the average velocity of the car during the time that it is moving between the...

A car traveling 93 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.85 m . What was the magnitude of the average acceleration of the driver during the collision? Express the answer in terms of "g's," where 1.00g=9.80m/s2.

PLEASE HELP ASAP
A 1000 kg car moving at 5.8 m/s is initially traveling north in the positive y direction. After completing a 90° right-hand turn to the positive x direction in 4.3 s, the inattentive operator drives into a tree, which stops the car in 220 ms. What is the magnitude of the impulse on the car (a) due to the turn and (b) due to the collision? What is the magnitude of the average force that acts on...
