Aball having a mass of 200 g is released from rest at a height of 400 mm above a very large fixed metal surface. if the ball rebounds to a height of 325 mm above the surface, determine the coefficient of restitution between the ball and the surface.

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
