JEE Main Physics question
The backside of a truck is open and a box of 40 kg is placed 5 m away from the rear end. The coefficient of friction of the box with the surface of the truck is 0.15. The truck starts from rest with 2 m/s² acceleration. Calculate the distance covered by the truck when the box falls off
Answer: (A)
Solution
Since the truck's acceleration (2 m/s²) exceeds the maximum friction-driven acceleration of the box (μg = 1.5 m/s²), the box slides backward relative to the truck bed, with relative
