A Person in "Free Fall" Newton's 2nd Law
An 80kg aviator is in free fall and acquires a velocity of 60 m/s and then opens his parachute.
After falling an additional 30m, his velocity has been reduced to 20 m/s. What is the average acceleration of the aviator while his fall is being checked? What is the average force being exerted by the parachute?
Force = Mass * acceleration
Average acceleration = change in velocity/change in time
Any help would be appreciated, Dont understand how to go about problem
