Physics problem?

Question

If a 1.8 x 103 kg brick falls to the ground from a cliff that is 6.7 x 102 m high, what is the change in its potential energy?

Answer 1

your numbers don't make sense. but anyway...

If a 1.8 x 103 = 185.4 kg brick falls to the ground from a cliff that is 6.7 x 102 = 683.4 m high, what is the change in its potential energy?

PE = mgh = (185.4)(9.8)(683.4) = ____ J
