A smooth inclined plane has length 10 m and the angle of inclination is 30⁰. A body of mass 2 kg is released from rest at the top of the inclined plane. What is its acceleration down the inclined plane?

A cricket player catches a ball of mass 100 g and moving with a velocity of 25 ms^-1. If the ball is caught in 0.1s, the force of the blow exerted on the hand of the player is

A body of mass 2 kg ,moving on a horizontal surface with an initial velocity of 4 m/s , comes to rest after 2 s.If one wants to keep this moving on the same surface with a velocity of 4 m/s,the force required is

A boy of mass 50 kg is standing on a weighing machine placed on the floor of a lift.The machine reads his weight in Newtons.What is the reading of the machine if the lift is moving upwards with a uniform speed of 10 m/sec²?

(g = 10 m/sec² )

What should be the tension in a rope pulling vertically upward a mass of 100 kg so that starting from rest it acquires a velocity of 4 m/s in 1.5 seconds?

Two forces of 6N and 8N act on a body of mass 7kg. The maximum value of acceleration produced cannot be more than

A lift is moving upward with increasing speed with acceleration 'a'.The apparent weight will be :

A light string passing over a smooth light pulley , connects two blocks of masses m₁ and m₂ (vertically).If the acceleration of the system is (g/8),then the ratio of masses is

A block of metal of mass 2 kg is resting on a frictionless floor.It is struck by a jet releasing water at the rate of 1 kg/sec and at a speed of 5 m/s.What will be the initial acceleration of the block ?

Physical independence of force is a consequence of
