A motorcycle is moving with a velocity of 90 km//h and it takes 5 second to stop after the brakers are applied. Calculate the force exerted by the brakers on the motorcycle if its mass alongwith the rider is 200 kg

A car of mass 1000 kg moving with a velocity of 36 km/h comes to rest in 5 seconds. What is the force exerted on the car?

A car travelling at the speed of 108 km//h takes 4 s to stop on applying brakes. Calculate the force acting on the car after applying brakes. Total mass of the(including passengers) is 1000 kg.

A rifle of mass 3 kg fires a bullet of mass 0.03 kg. The bullet leaves the barrel of the rifle at a vleocity of 100 m/s. If the bullet takes 0.003 second to move out of the barrel, calculate the force experienced by the rifle due to its recoil. Initially rifle+Bullet system at rest

A ball of mass 100 g moving with a velocity of 10ms^-1 is stopped by a boy in 0.25sec. Calculate the force applied by the boy to stop the ball.
