Motion of system of Particles and Rigid Body
A particle moves along a circle of radius 20/π m with constant tangential acceleration
A particle moves along a circle of radius 20/π m with constant tangential acceleration. If the velocity of the particle is 80m/s at the end of the second revolution after motion has begun, the tangential […]
