[QUE/ME-08001] ME-PROBLEM

A man is standing in a bus moving with a speed of 97 km/hr. The driver suddenly applies brakes. The bus decelerates at the rate of \(g/10\). Will the man tend to fall in forward, or in backward direction?

1. Draw a diagram to show all the forces on the man in the car as seen
   • in the frame of reference fixed in the car.
   • in an inertial frame fixed with respect to the ground outside the car.
2. Find the net force experienced by the person in two ways by working in the two frames as given above.
3. Is the force felt by the man a pseudo force? his imagination \frownie ? or a real force? If real force, what is the source of this force? What supplies this force as seen in the inertial frame? \hfill[4+4+2]
