Which statement describes how a machine can help make work easier?
O It can put out more force than the input force by decreasing the distance over which force is applied.
O It can increase the amount of work performed if the output force is in the same direction as the input force.
O It can apply a greater output force over a greater distance compared to the input force and distance.
It can increase the distance over which output force acts by applying less output force than input force.

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
