100%
Each of the following equations describes the motion of a particle moving along the unit circle in the ry-plane. However, the dynamics are different in each case. In each
case, determine whether the particle has constant speed, whether the particle's acceleration is always orthogonal to its velocity, which direction the particle travels, and where the
particle begins.
