   1. The problem statement, all variables and given/known data
   
   Fred (mass 50.0 kg) is running with the football at a speed of 6.10 m/s when he is met head-on by Brutus (mass 130 kg), who is moving at 5.10 m/s. Brutus grabs Fred in a tight grip, and they fall to the ground. How far do they slide?The coefficient of kinetic friction between football uniforms and Astroturf is 0.330 .
   
   2. Relevant equations
   
   
   
   3. The attempt at a solution

   Danielle_6,
   
   You got to try something before we can help you. At least a guess. What is the formula for kinetic energy? How does force relate to coefficient of kinetic friction? TRY!!
