There are two objects of mass ‘m’ connected over a frictionless pulley and are moving with velocity ‘v’.Inertia of pulley and friction is neglected.It is desired that the arrangement shd hv a max stopping time of ‘t’ from peak speed of ‘v’.What shd b the minimum power of the motor?(GATE 05 Mechanics question)
Options:
1)0.5*m*v*v
2)0.5*m*v*v/t
3)m*v*v/t
4)2*m*v*v/t
