How much work must be done to stop a 1200-kg car traveling at 145 km/h ?
a 700 kg car is waiting at a stop light, when a 1200 kg car coasting at 4.0m/s strikes it from the rear. the cars do not stick together, nor is the collision perfectly elastic. The front car moves ahead at 5m/s after the collision. What is the speed of the rear car after the collision?

Calculate the thermal energy dissipated from brakes in a 1200kg car that descends a 16? hill. The car begins braking when its speed is 90km/h and slows to a speed of 30km/h in a distance of 0.30km measured along the road.
Consider a car with mass M. If the car has an initial speed of vo and a maximum braking force of Fb, write an expression for the stopping distance, i.e. the distance needed to stop if the full braking force is applied.Calculate the stopping distance for M = 1250 kg, vo = 14.0 m/s, and Fb = 2580 N.
A 1200 kg car is practicing on a flat test track. The car begins moving in a 100 m radius circle at a speed of 20 m/s. Viewed above, it is traveling around the circle clockwise, beginning from the top of the circle. (A) What is the centripetal acceleration of the car? (B) How much force is required for this? (C) What is the coefficient of friction between the tires and the track? Three quarters of the way around the...
For a car braking with constant deceleration, the time to stop is doubled when the speed of the car before braking is doubled.

Use the work-energy theorem to determine the force required to stop a 1100-kg car moving at a speed of 25.0 m/s if there is a distance of 55.0 m in which to stop it.
