A particle of mass m falls from rest at a height of 16 m and is brought to rest by penetrating 1/6 m into the ground. If the average vertical thrust exerted by the ground be 388 kg. wt, then the mass of the particle is

A light string passing over a light smooth pulley carries masses of 3 kg and 5 kg at its ends. If the string breaks after the masses have moved 9 m, then the 3 kg mass will farther rise (g = 10 m/sec²)

A light string passing over a light smooth pulley carries masses of 3 kg and 5 kg at its ends. If the string is allowed to move from the rest the acceleration of the motion is equal to

Two bodies of mass 8 and 10 gm is attached to a light rope which is passing over a smooth pulley. If this system is given to a velocity 3/16 g cm/sec, then small body will move downwards and heavy body will move upwards, then after what time they will move in opposite directions?

Two masses m₁ and m₂ are connected by a light inextensible string and suspended over a smooth fixed pulley. Then

Two masses are attached to the pulley as shown in fig., find acceleration of centre of mass

Two equal perfectly elastic balls impinges directly, then after impact they

A sphere impinges directly on an equal sphere at rest. If the coefficient of restitution is e, their velocities after the impact are as

A ball is dropped from a height of 22.5 metre on a fixed horizontal plane. If e =2/5, then it will stop rebounding after

An elastic ball with coefficient of elasticity 1/2 is dropped from rest at a height h on a smooth floor. The total distance covered by the ball is
