Problem
A 2.0kg crate starts from rest and is pulled horizontally by a constant 15N force along a surface with a coefficient of kinetic friction μk=0.20. Derive and state a simplified algebraic expression for the instantaneous net power P(t) (in watts) delivered to the crate as a function of time t (in seconds).
