Question:medium

A truck of mass 8 ton is carrying a block of mass 2 ton. If a breaking force of 25 kN is applied on the truck, then the frictional force acting on the block is (Coefficient of static friction between the block and the truck is 0.3)

Show Hint

In problems with friction between two moving objects, first calculate the acceleration of the system as if they were a single object. Then, isolate the top object and determine the frictional force required to produce that acceleration. Finally, compare this required force to the maximum static friction to see if slipping occurs.
