Teaching BPSC 4.0 बिहार उच्च माध्यमिक शिक्षक भर्ती (PGT) Mock Test Physics Motion in a Straight Line Kinematic equations for uniformly accelerated motion
The rear side of a truck is open and a box of 30 kg mass is placed 4.5 m away from the open end as given in the diagram. The coefficient of friction between the box and the surface below it is 0.20. On a straight road, the truck starts from rest and accelerates with 3 m/s2. At what distance from the starting point does the box fall off the truck? (ignore the size of the box) (Let g = 10 m/s2)
