Help!!! Not sure what im doing wrong A 11.4 g bullet is fired horizontally into a 94 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 0.650, what was the speed of the bullet immediately before impact? m/s first thing i did was find the block speed t = sqrt((7.5)(.65)/9.8) t = .7053 then i did V = deltax/t = 7.5/.7053 = 10.6338 mv_1 + Mv_2 = (m + M)V V = 98.31 which is incorrect but answer is within 10% of the correct value. I am not sure if im doing this correctly or im just completely off.
