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

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 small body of mass 1kg is projected with initial velocity 10sqrt2 m//s on a rough horizontal surface. The coefficient of friction between the body and surface varies as mu = 5x where x is the displacement of the body. The distance travelled by the body before coming to rest__

A small body is projected with a velocity of 20.5 ms^(-1) along rough horizontal surface. The coefficient of friction (mu) between the body and surface changes with time t (in s) as the the body moves along the surface. Find the velocity at the end of 4s in m/s
