1. A 0.342- kg coffee mug rests on a table top 0.67 m above the floor. What is the potential energy of the mug with respect to the floor?
Answer: 2.25J
B. What is its potential energy with respect to a counter top 1.1 m above the floor?
Answer:?
P.E.=mgh
i thought that i would do the problem exactly the same as i did the first.
(0.342)(9.8)(1.1)= P.E. because for the first problem i used the same thing except for 1.1 instead i used 0.67 for the first problem. The answer that i get for the second problem is 3.68676J but I'm told this is not right.
any help would be appreciated.
