comprehensive problems 1.You may use this way to get a bullet speed. Suppose a bullet of mass 8.00 g is fired into a block of mass 2.50 Kg initially at rest at the edge of a frictionless table of height 1.00m. The bullet remains in the block, and after impact the block lands a distance 2.00 m from the bottom of the table, Determine the initial speed of the bullet. (review perfectly inelastic collision and projectile motion. V(bullet) = 1388m/s)

(2) A ball of mass m is attached to a string of length L. It is being swung in a vertical circle with enough speed so that the string remains taut throughout the ball's motion. Find : (1) Tb-Tt, the difference between the tension in the string at the bottom relative to that at the top of the circle in terms of m, g ( see your homework #7) (2) find the centripetal acceleration difference at the bottom and the top
