10 Points A Force of F(x) = x2 – cos(3x) +2, where x is in meters, acts on an object with a mass of 2.5 kg.  What is the work required to move the object from x = 3 to x = 7?  How much Power is produced during this event that takes 2.75 seconds to complete?

15 Points A ball is mass 4 m is dropped from rest from a height of 10 meters above the ground.  It undergoes a perfectly elastic collision with the ground and rebounds.  At the instant the ball rebounds, a small piece of clay is released from rest from the original height h, directly above the ball, as shown on the right diagram.  The clay, which is descending, eventually collides with the ball, which is ascending. Determine the speed of the ball immediately before it hits the ground Determine the height above the ground at which the collision takes place. Determine the speed of the ball and the clay immediately before the collision. If the ball and the clay stick together on impact, what is the magnitude and direction of their velocity immediately after the collision?
