The rear side of truck is open and a box of mass 50kg is placed at 3.2m away from the open end. The co-efficient of friction between the box and the surface is 0.2. If the truck starts from rest and moves on a straight road with acceleration 2.1ms^(-2) the box falls off the truck after a time (g=10ms^(-2))

1.	The rear side of truck is open and a box of mass 50kg is placed at 3.2m away from the open end. The co-efficient of friction between the box and the surface is 0.2. If the truck starts from rest and moves on a straight road with acceleration 2.1ms^(-2) the box falls off the truck after a time (g=10ms^(-2))
