A car of mass `1000kg` moves from point `A` to `B`. If kinetic energy of car at point `A` is `100KJ` and at `B` is `220 Kj`. Then find work done by friction force on the car ?

A car is moving with a constant speed on a straight line. What is the net work done by the external force on the car?

A skater of mass 50 kg moves down from A to B. The frictional forces are absent. What is the kinetic energy at B?

A car of mass 1000kg moves on a circular path with constant speed of 12 m//s . It turned through 90^@ after travelling 471 m on the road . The centripetal force acting on the car is

A car of 500 kg mass has a kinetic energy of 64 kJ. Find is speed ( in m/s)

Car A of mass 1000 kg moves on a horizontal straight road with speed 36kmh^(-1) . If the force resisting the motion is 100 N, then find the power of the engine. Now, after covering 200 m distance, car A collides with a stationary car B of same mass and becomes stationary. As a result car B start moving on the horizontal road, then what would be the speed of car B just after the collision? (The engine of car B is off.)

A car of mass 1000 kg is moving with a certain speed when a constant braking force 1000 N acts on it for 5s and the speed of the car reduces to half its original speed. Find the further time required to stop the car if the same constant force acts.
