The boy is pulling a sled across the snow. Which of the following statements is true if the sled is slowing down? The forces acting on the sled are balanced
The net force is in the same direction that the sled is being pulled.
The force exerted by the rope on the sled is larger than the force of friction.
The force of friction on the sled is larger than the force of the rope pulling on the sled

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
