Determine the center of mass of a uiform cone of height h and radius R, with its axis pointing along z. (Hint: use the symmetry about the z axis. What is the mass dm of a thin disk o thickness dz at height z as shown in the drawing? How is r/z related to R/h? Remember to use M = f dm.) R dz dm IN

FI R %24 Part A A ball of mass m moving with velocity v strikes a vertical wall as shown in (Eigure 1). The angle between the ball's initial velocity vector and the wall is 6 as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is At, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the force exerted on the ball by the wall is parallel to the x axis. What is the final angle Or that the ball's velocity vector makes with the negative y axis?
