Acar of 1000 kg with good tires on a dry road can decelerate (slow down) at a steady rate of about 5.0 m/s2 when braking. if a car is initially traveling at 20 m/s (45 mi/h), (a) how much time does it take the car to stop? (b) what is its stopping distance? (c) what is the deacceleration? (d) how big is the net force to be applied to stop this car? (e) calculate the work done by this force (work = force * distance). (f) during the stopping process, what happens to the car's kinetic energy?
