Question
The 20-lb crate A rests on the surface. The coefficients of static and kinetic friction between
the crate A and the surface are ?? = 0.15, ?? = 0.1. Determine the speed of crate A at t = 2 s if P =
(?
2 + 1.5?) lb where t is in seconds, using the method of Linear Impact and Momentum. Hint: first
determine the moment when the crate starts to move.
