# A parachutist with a mass of 80 kg is falling at 55km/h when her parachute opens. She then falls 24 m in the next 2 s. What is the force of air resistance acting on the parachute during those 2 s?

##### 1 Answer

#### Explanation:

This is the velocity at the time of parachute opens.

Take this moment as

There will be acceleration due to gravity '

So the effective acceleration will be

Here initial velocity is

Solving this we get the value of

Force

The force of air resistance will be
