a block of metal weighing 2kg is resting on a frictionless plane.it is struck by a jet releasing water at the rate of 1kg/sec at a speed of 5m/s.find the initial acceleration of the block.
F = v dm/dt =5*1=5N
Under this force 5 N, the block of mass 2 kg will move with an acceleration given by
a= F/ m = 2.5m/s2 ans..
