Auniform beam of length l and mass m has its lower end pivoted at p on the floor, making an angle θ with the floor. a horizontal cable is attached at its upper end b to a point a on a wall. a box of mass m is suspended from a rope that is attached to the beam one-fourth l from its upper end.

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.)
