A particle of mass m, moving in a circle of radius R, has a velocity `v=v_(0)(1-e^(-gamma t))` The power delivered to tha particle by the force at `t=0` is

A particle is moving in a circle of radius R in such a way that at any instant the tangential retardation of the particle and the normal acceleration of the particle are equal. If its speed at t=0 is v_(0) , the time taken to complete the first revolution is

A particles of mass m moving in a circle of radius r with unform speed v . The force F acting on a particle is proportional ot m^(a) v^(b) r^(c ) . Find the values of a, b and c.

A particle of mass m, moving with a constant acceleration , acquires a velocity v_0 in time t_0 . Initially the particle was at rest. Find the average power and the instaneous power of the applied force.

A particle of mass M is moving in a circle of fixed radius R in such a way that its centripetal acceleration at time t is given by n^2Rt^2 where n is a constant. The power delivered to the particle by the force acting on it, it :

A particle of mass m has a velocity -v_(0) i , while a second particle of same mass has a velocity v_(0) j . After the particles collide, first particle is found to have a velocity (-1)/(2) v_(0) overline i then the velocity of othe particle is
