An 85 kg person is parachuting and experiencing a downward acceleration of 2.5 m/s2. The mass of the parachute is 4.8 kg.(adsbygoogle = window.adsbygoogle || []).push({});

What downward force is exerted by the person on the parachute?

>>What i am [was] thinking << ::

Well, i tried to solve it by using by using this method its wrong 'its online homework'

First, i assume that it should be Zero, since both are in the same system moving with the same accelaration, but it show wrong.

Then i try to solve by Total Force= Force of Gravity on the body + Force of Gravity on the Parachute + Force of Air (-) + Force of body on the parachute. and it did not help as well :( [the Air force is 655.54N as a correct answer]

Thank in advance for helping, i appreciate it.
