A particle of mass 2kg start motion form rest on a circular path of radius r=4m with constant tangential acceleration 4 ms^(-2) . Find the net work done on the particle in initial 1 second.

Define centripetal force.A particle of mass m is rotating around a circular path of radius r. Find the centripetal acceleration of the particle and the magnitude and direction of the centripetal force acting on it.

A particle is moving along a circular path of radius 0.7 m with constant tangential acceleration of 5 m cdot s^(-2) . The particle is initially at rast. Based on the above information, answer the following questions : The radial acceleration of the particle at t = 7 s is
