Question

A particle is rotating in a horizontal plane about a fixed axis. The radius of its circular path is 5.0 m and it starts to rotate at a constant angular acceleration from rest at time t = 0. The angular speed of the particle reaches 8.0 rad/s at t = 8.00 s. Find the magnitude of the particle's angular velocity (in rad/s) at t = 4.00 s.
