The force of a plane's engine is moving the plane toward the right with 800N. Coming from the left you have resistance forces of air with 60N and friction with 40N. What is the direction and net forces that is being applied
the plane?

No bc a lot of things r still theories n unproven

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

Answer the above statement is ( false );
