A 10.0 gram wad of sticky clay is hurled horizontally at a 95 gram wooden block initially at rest on a horizontal surface. The clay sticks to the block. After impact, the block slides 7.50 meter before coming to rest. If the coefficient of friction between block and surface is 0.650, obtain the speed of the clay immediately before impact? m/s
