Vedclass · Answer

(A) When the car is in the air,it is in a state of free fall under the influence of gravity alone. In this state,the acceleration of the car and the driver is $a = g$ (downwards). If we analyze the motion from the frame of reference of the driver,we apply a pseudo force $F_p = m g$ acting in the upward direction. The actual weight of the driver is $W = m g$ acting in the downward direction. The net force on the driver in their own frame is $F_{net} = F_p - W = m g - m g = 0$. Since the net force acting on the driver is zero,they experience a state of weightlessness throughout the entire duration of the flight.

$A$ stunt man jumps his car over a crater as shown (neglect air resistance).
