Question

A man weighing 50 kg jumps from a hot air balloon and reaches a constant velocity during the fall. After a minute, he opens a parachute and reaches a constant velocity again. Which two graphs together can show the approximate upward and downward forces on the skydiver?
Assume upward force as positive.

Solution

The correct option is E III and IV
Downward force is always - 500N because of his weight,therefore IV graph. Upward force is because of the air resistance and it is positive always. Upward force increases so that the man reaches a constant velocity. Then the parachute opens up and the force again increases to reduce the velocity which can be seen from third graph.

Q. (a) A sky diver jumps out of a plane. After he reaches terminal velocity, he opens his parachute. Of the two forces- the air resistance and gravity acting on the sky diver after the parachute opens, which is greater.
(b) Air being a fluid produces a small buoyant force on the skydiver. How does the buoyant force change after he opens his parachute? Why?
Q. A hot air balloon is rising vertically upwards at a constant velocity of 10 ms−1. When it is at a height of 45 m from the ground, a man bails out from it. After 3 s he opens his parachute and decelerates at a constant rate of 5 ms−2. How far is parachutist from the balloon at t=3 s?
