A car weighing 1000 kg and travelling at `30 m//s` stops at a distance of 50 m decelerating uniformly. What is the force exerted on it by the breaks ? What is the work done by the brakes?

A car weighing 1000 kg is travelling at the speed of 15ms^(-1) . It decelerated due to brakes applied and stops after covering a distance of 25 m. Find the force exerted by the brakes and the work done by the brakes.

A car of mass 1000 kg is moving at 25m/s is brought to rest over a distance of 50 m. Find the breaking force and time required to stop.

A car of 1000 kg moving with a velocity of 30 m//s stops with uniform acceleration after covering a distance of 50 m on application of brakes. Find the force applied by the brakes on the car and also work done.

A car of 1000 kg moving with a velocity of 30 m//s stops with uniform acceleration after covering a distance of 50 m on application of brakes. Find the force applied by the brakes on the car and also work done.

A car weighing 500 kg moving against a resistance of 500 N, accelerates from rest to 20 m//s in 100m (g = 10m//s^2). The work done by the engine of the car is :
