Okay this is question is confusing me. Kinetic energy (KE) has dimension kg * m^2 / s^2 and can be written in terms of the momentum (p) and mass (m) as: KE = (p^2) / 2m.
a) Determine the proper units for momentum using dimensional analysis.
So this is what I did so far: [KE] = [kg] * [m^2] / [s^2] = p^2 / m.
I know that the units of momentum are kg * m / s and that is what I should end up with, but I don't know the steps to get there. Do I need to solve for p or what? I don't know how I could since p is squared. Please help I'm very confused.
