A particle is revolving in a circle of radius 1m with an angular speed of 12 rad/s. At t=0, it was subjected to a constant angular acceleration α and its angular speed increased to (480/π) rotation per minute (rpm) in 2 sec. Particles then continues to move attained speed. Calculate
angular acceleration of the particle
tangential velocity of the particle as a function of time.
acceleration of the particle at t=0.5 second and at t=3 seconds
angular displacement at t=3 seconds
