A crate of mass 55.6 kg is being transported on the flatbed of a pickup truck. The coefficient of static friction between the crate and the trucks flatbed is 0.330, and the coefficient of kinetic friction is 0.320.
(b) The truck barely exceeds this acceleration and then moves with constant acceleration, with the crate sliding along its bed. What is the acceleration of the crate relative to the ground?
ma=F(fr) = μ(s) •N= μ(s) •m•g,
ma1=F1(fr) = μ(k) •N= μ(k) •m•g,
