A crate of mass 45.0 kg is being transported on the flatbed ofapickup truck. The coefficient of static friction between thecrateand the truck's flatbed is 0.350, andthe coefficient ofkinetic friction is 0.240.
(a) The truck accelerates forward onlevelground. What is the maximum acceleration the truck can have sothatthe crate does not slide relative to the truck's flatbed?
1 m/s2
(b) The truck barely exceeds this acceleration and then moveswithconstant acceleration, with the crate sliding along its bed.Whatis the acceleration of the crate relative to the ground?
