. A hammer of mass 200g is dropped from the top of the roof of a two-storey building to the ground. Another hammer of equal mass fell from the coffee table to the ground. Given that the height of the two-storey building, and the coffee table are 10 m and 1.2m respectively. Show that a hammer dropped from two store building roof does more work than a hammer falling from a coffee table. ​
