Laws Of Motion Mock Tests

A car moving at 36 km/h is brought to rest by applying brakes. If the coefficient of friction is 0.5, the distance covered before stopping is: (g = 10 m/s²)

A block of mass 5 kg rests on a horizontal surface with coefficient of static friction 0.4. The minimum horizontal force required to just move the block is: (g = 10 m/s²)

A ball of mass 0.5 kg moving at 10 m/s collides with a wall and rebounds with the same speed. If the contact time is 0.1 s, the average force exerted by the wall is:

A body of mass m is rotating in a vertical circle. The difference between the tensions at the lowest and highest points is:

A car of mass 1000 kg moves on a circular track of radius 20 m. If the coefficient of friction between the tyres and the road is 0.5, the maximum speed with which the car can move without skidding is: (g = 10 m/s²)

A body of mass 5 kg is acted upon by two perpendicular forces of 3 N and 4 N. The magnitude of the acceleration of the body is:

A body of mass 10 kg is moving with velocity 10 m/s. A force acts on it for 5 s, after which the velocity becomes 2 m/s in the opposite direction. The force is:

A force of 10 N acts on a body of mass 2 kg for 3 s, imparting an impulse. The change in velocity of the body is:
