Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

1- (Fall 2002) A person with a closed parachute jumps out of an airplane and falls freely for
100m. The parachute then opens and the person decelerates at 2m/s². The person
reaches the ground with a speed of 3 m/s.
a) How long was the person in the air?
b) At what height was the airplane flying?
