Speed of the first block immediately before impact

Reference no: EM13564646

A 145 g block hits a 115 g block initially at rest on a horizontalsurface. After impact they stick together and slide 9.01 m beforecoming to rest. The acceleration of gravity is 9.8 m/s^2. If thecoefficient of friction between blocks and surface is 0.417, whatwas the speed of the first block immediately before impact?
