A spy jumps from an airplane with his pasrachute. The spy accelerates downward for some time when the parachute opens. The acceleration is sudenly checked and the spy slowly falls on the ground. Explain the action of parachute in checking the acceleration.

A paratrooper id dropped from an airplane. After some time his parachute opens and he reaches the ground with almost zero speed. This speed of fall (v) versus time (t) grapg will look like :

In the climax of a movie, the hero jumps from a helicopter and the villain chasing the hero also jumps from the same level . After sometime when they come at same horizontal level, the villain fires bullet horizontally towards the hero, Both were falling with constant acceleration 2(m)/(s^2), because of parachute, Assuming the hero to be within the range of bullet, which of the following is correct.

A ballon starts risintg from ground from rest at some constant acceleration. After some time, a storne is dropped from it. If the stone reaches the ground in the same time in which balloon reached the dropping poing from ground, find the acceleration of the balloon.

A parachutist after bailing out falls 80 m without friction. When the parachute opens, he decelerates downward with 5m//s^(2) and reaches the ground with a speed of 10 m//s . (a) How long is the parachutist in air? (b) At what height did bail out?

A parachutist drops freely from an aeroplane for 10 seconds before the parachute opens out. Then he descends with a net retardation of 2 m//s^(2) . His velocity when he reaches the ground is 8 m//s find the height at which he gets out of the aeroplane?

A parachutist after bailing out falls for 10 s without friction. When the parachute opens he descends with an acceleration of 2 m//s^(2) against his direction and reached the ground with 4 m//s from what height he has dropped himself? (g=10 m//s^(2))

A lift accelerates downwards from rest at rate of 2 m//s^(2) , starting 100 m above the ground. After 3 sec, an object falls out of the lift. Which will reach the ground first? What is the time interval between their striking the ground?

A parachutist steps from an aircraft, falls freely for two second, and then opens his parachute. Which of the following acceleration time (a - t) graphs best represents his downward acceleration a during the first 5 second ?
