A 25 g bullet is fired horizontally with an initial velocity and becomes embedded in a 3 kg block resting on a horizontal surface. After impact, the block strikes a 1 kg clay resting 0.5 m away and slides down a smooth inclined chute. Knowing the impact is perfectly plastic and the coefficient of kinetic friction between the block and the horizontal I. surface is 0.2, determine a) the height "h " below the horizontal surface in order that the block may make a complete circuit in the 2 m diameter loop; b) the initial velocity of the bullet.
