The rear side of a truck is open and a box of 40kg mass is placed 5m away from the open end as shown in the figure. The coefficient of friction between the box and the surface below it is 0.15. On a straight road, the truck starts from rest and accelerates with 2ms−2. Find the distance (in m) traveled by truck by the time box falls from the truck. (Ignore the size of the box)
