02.10 Free Fall Motion what would be the acceleration due to gravitational force?
Dropped at height 2.286m and 1.905m. Landed in 0.89s and 0.62s. My teacher told me to start with d=(1/2)at^2. I just need to know the acceleration due to gravitational force for 2.286m in 0.89s and 1.905m in 0.62s. Thanks

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
