Question
Basic science, A hammer of mass is dropped from thew top of a roof of the two storey building to the ground. Another hammer of equal mass fell from a coffee table to the ground. Given than the height of the two storey building and the coffee table are 10m and 5m respectively.
(A) show that a hammer dropped from two storey building roof does more work than a hammer falling from a coffee table (6)
(B) calculate the potential energy from the two heights (4)
