A body of mass `2kg` is projected vertically up with velocity `5ms^(-1)`. The work done on the body by gravitational force before it is brought to rest momentarily is

A body of mass 2 kg is projected vertically upward with a velocity of 2msec^(-1) . The K.E. of the body just before striking the ground is

A body of mass 2 kg is projected with an initial velocity of 5 ms^(-1) along a rough horizontal table. The work done on the body by the frictional forces before it is brought to rest is
