Question

a body of mass 10 kg is moving at the constant speed of 20 m per second over a frictionless surface. the work done by the weight is

Answer 1

as object is moving at constant speed....acc is zero ...hence force is also zero ..... because force = mass x acc
and as force is zero ....wrok done is also zero as workdone = force x displacement
