Question 5: A particle of mass m is moving in a circular path of radius R as shown in Figure 3. The angular speed of the particle is given by w = ßt3/2. Find the tangential and the radial (centripetal) forces acting on the particle as a function of time t. In Figure 3, 0 and î are the tangential and radial unit vectors. Is the motion uniform or non-uniform? Explain your answer briefly. Figure 3

Question 5: A particle of mass m is moving in a circular path of radius R as
shown in Figure 3. The angular speed of the particle is given by w = Bt3/2. Find
the tangential and the radial (centripetal) forces acting on the particle as a function
of time t. In Figure 3, Ô and î are the tangential and radial unit vectors. Is the motion
uniform or non-uniform? Explain your answer briefly.
