Q.
Figure shows a man of mass 55kg standing stationary with respect to a horizontal conveyor belt that is accelerating with 1ms−2. The net force acting on the man is
Here, mass of the man, M=55kg
As the man is standing stationary w.r.t. the belt, acceleration of man = acceleration of belt. ∴ Acceleration of man, a=1ms−2 ∴ Net force on the man F=Ma=(55kg)(1ms−2)=55N
