A playground slide is 7.50 ft long and makes an angle of 34.0° with the horizontal. A 59.0-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.)

Utop

 =  J

Ubottom

 =  J

ΔU

 =  J


(b) Repeat part (a), choosing the top of the slide as the reference configuration. (Include the sign of the value in your answer.)

Utop

 =  J

Ubottom

 =  J

ΔU

 =  J

Solutions

Expert Solution

The concept used is of gravitational potential energy , reference configuration decides the value of potential energy at the bottom and at the top , all the measurement is measured on the basis of reference configuration , finally after applying this concept i deduced the value of potential at the top and bottom and the change in potential energy.
