Answer 1
20 J
INCORRECT
error in calculations. Try again! GPE = mgh return to top
Answer 2
200 J
CORRECT
GPEc = mgh
GPE = (10 kg) (10 m/s2)(2.0 m)
GPE = 200 J return to top
Answer 3
300 J
INCORRECT
error in calculations. Try again! GPE = mgh return to top
Answer 4
500 J
INCORRECT
error in calculations. Try again! GPE = mgh return to top
