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 115 km/h in 8.28 s before striking a simulated deer. The car is in contact with the faux fawn for 0.575 s, after which the car is measured to be traveling at 71.0 km/h. What is the magnitude of the acceleration of the car before the collision? acceleration before collision: m/s2 What is the magnitude of the average acceleration of the car during the...

1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...

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.

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 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...

1) A car is traveling at a steady 77km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 7.3m/s2 . a)How much time elapses before the motorcycle is moving as fast as the car? b)How far is the motorcycle from the car when it reaches this speed? 2)A gannet is a seabird that fishes by diving from a great height. If a gannet hits the water at 32m/s...
