small block of mass 200 g is kept at the top of a frictioinless incline which is 10 m long and 3.2 m high. How much work was required a. to lift the block from the ground nd put it at thetop b. to side the block up the incline? What will be the speed of the block when it reaches the ground if, c. it falls off the incline and drops vertically on the ground d. it slides down the incline? Take `g=10 m/s^2`.

A block is released from rest at the top of a frictionless inclined plane, which is 10 m long. It reaches the bottom in 5 seconds.A second block is projected up the plane from the bottom at the instant the first block is released and the two return to the bottom simultaneously.(a)Find the acceleration of each block along the incline.(b)What is the initial velocity of the second block ? (c )How far up the inclined plane does it travel ?

A small block of mass 2kg is kept on a rough inclined surface of inclination theta=30^@ fixed in a lift. The lift goes up with a uniform speed of 1ms^-1 and the block does not slide relative to the inclined surface. The work done by the force of friction on the block in a time interval of 2s is
