1. The problem statement, all variables and given/known data Use the Work-Energy Theorem to show that an object with initial velocity vo will travel a distance d across a rough horizontal surface before stopping, where d = vo2/(2muKg). 2. Relevant equations W = delta KE = mV^2/2 3. The attempt at a solution To be honest, I have absolutely no idea where to even start. Any suggestions on how to start would be greatly appreciated.
