  • Question 1/10
    4 / -1
    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
    Solutions

  • Question 2/10
    4 / -1
    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)
    Solutions

  • Question 3/10
    4 / -1
    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
    Solutions

  • Question 4/10
    4 / -1
    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?
