Question

suppose you do 1000 j of work on a 5 kg object, and all the work went into lifting it above the ground. how high above the ground will the object be when all the work has been done? group of answer choices

Answer 1

P. E = mgh

when g= 10ms^-1

1000j = 5 × 10 × h

1000j = 50h

h = 1000 ÷ 50

h = 2Om
