1) What will be the speed of a solid sphere of mass M and radius R0 when it reaches the bottom of incline if it starts from rest at a vertical height of H and rolls without slipping? Compare to the case of an object sliding down with no rotation. (replace the variables with any number)
2) A bullet of mass m and v strikes and becomes imbedded at the edge of a cylinder of mass m and radius R0. The cylinder, initially at rest, begins to rotate about its symmetry axis, which remains fixed is the position. Assuming no frictional torque. What is the angular velocity of the cylinder after the collision? ( replace the variables with any number)

A solid sphere of mass M and radius R sits on a an incline of angle θ, when it is let go it rolls down-hill without slipping at total vertical distance of h. At the bottom of the hill the ball moves onto a horizontal surface and enters into a completely elastic collision with a stationary block of height 2R and mass 2M. Find the speed of the block right after the collision.
