Q.27. A parachutist speeds up as he falls down towards ground, until he attains a constant speed. How would you describe the force of air resistance that acts on him?
a) It decreases as he goes faster until it is less than the weight of the parachutist.

Q. A parachutist after bailing out falls 80 m without air resistance. Then the parachute is opened, and he decelerates at a uniform rate of

2 m / s^{2}

. If he reaches the ground with a speed of

4 m / s

, then the height at which he bailed out is [

g = 10 m / s^{2}

Q. A parachutist after bailing out falls

50 m

without friction. When parachute opens, it decelerates at

2 {m/s}^{2}

. He reaches the ground with a speed of

3 m/s

. At what height, did he bail out ?

A rain drop of radius 2 mm falls from a height of 500 m above the ground. It falls with decreasing acceleration (due to viscous resistance of the air) until at half its original height, it attains its maximum (terminal) speed, and moves with uniform speed thereafter. What is the work done by the gravitational force on the drop in the first and second half of its journey? What is the work done by the resistive force in the entire journey if its speed on reaching the ground is 10 m s^–1?

Dear student Force of friction goes on increasing with increase in speed of the person and when it becomes equal to the weight of the person than the man acheive a constant velocity as net force on him becomes zero.Regards
