1. The problem statement, all variables and given/known data 2. Relevant equations L = I ω L= r x p 3. The attempt at a solution For b) My proffesor found the moment of inertia at the point at which the wheel touches the ground, and used the formula L = I ω What I dont understand is why can't one use L= r x p to solve the problem. Wouldn't L then simply be L=RMV?
