The rear side of a truck is open and a box of 40 kg mass is placed 5 m away from the open end as shown. The coefficient of friction between the box & the surface below it is 0.15. On a straight road, the truck starts from rest and accelerates with 2 ms−2. At what distance from the starting point does the box fall off the truck (i.e. distance travelled by the truck)? [Ignore the size of the box]
