Aparachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 58.8 m/s in 6.00 seconds. she then pulls the parachute cord and after a 4.00-second constant deceleration, descends at 10.0 m/s for 60.0 seconds, reaching the ground. from what height did the parachutist jump?

914m

Explanation:

We must divide the parachutist motion into three parts:

First we have free fall motion:

Then, we have a uniformly accelerated motion. The initial speed is this part will be the same final speed as the previous part.

Finally, we have a uniform linear motion:

The total heigh will be the sum of all heights:

answer; equivalent to a one(1) horsepower motor;
