Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_251

3/251 The coefficients of friction between the flat bed of the truck and crate are \(\mu_s = 0.80\) and \(\mu_k = 0.70\). The coefficient of kinetic friction between the truck tires and the road surface is 0.90. If the truck stops from an initial speed of 15 m/s with maximum braking (wheels skidding), determine where on the bed the crate finally comes to rest or the velocity \(v_{rel}\) relative to the truck with which the crate strikes the wall at the forward edge of the bed.
