physics momentum problems Fred (mass 70.0kg) is running with the football at a speed of 4.70m/s when he is met head-on by Brutus (mass 130kg), who is moving at 8.10m/s. Brutus grabs Fred in a tight grip, and they fall to the ground. How far do they slide? Part A The coefficient of kinetic friction between football uniforms and Astroturf is 0.290. Give answer in cm I got an answerof 13.1m/s=5.684m/s^2(deltaX) so ultimately deltaX=2.3 but what? meters? and could someone remind me of how to go from m to cm again.
