The diagram below shows a balloon rocket when the air in the balloon is released rocket will move forward which of the following statements best describes the force that causes the motion in the situation explained above The force of the released air is pushing backwards as the balloon gets smaller
The gravitational force is pulling down on the balloon as the air is released
The air outside the balloon pushes the balloon forward as it opposes the released air
The Force of the balloon is pushing up on all sides as the air is released

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
