horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total of your system‚ a bullet that is moving at a certain speed and a block that is stationary: Initial
