4. A 2144 kg car is traveling along a straight path at 31 m/s (approximately 70 mph). The driver then
employs the braking system to bring the car to a complete stop in 7.59 s. (You may assume the
acceleration is constant.)
A. Determine the magnitude of the force required to cause the acceleration.
B. Name and describe (in detail) the force that caused the acceleration.
C. Explain, in detail, how Newton’s First Law and Newton’s Third Law apply to the situation described in the problem statement

A car is traveling along a straight road at a velocity of +35.0 m/s when its engine cuts out. For the next ten seconds the car slows down, and its average acceleration is a1. For the next five seconds the car slows down further, and its average acceleration is a2. The velocity of the car at the end of the fifteen-second period is +24.2 m/s. The ratio of the average acceleration values is a1/a2 = 1.78. Find the velocity of...

Traveling at 40.2 m/s, a driver applies the brakes to his fast-moving car and skids out of control on a wet concrete horizontal road. The 2000 kg car is headed directly toward a student waiting to catch a bus to campus who is standing 58.0 m down the road. Luckily, Superman is flying overhead and surveys the situation. Knowing that the coefficient of kinetic friction between rubber and rough wet concrete is .800, he determines that friction alone will not...
