###### Question:

2. How much work does gravity do in causing a 6 kg hammer to fall to the ground from a

height of 10 m?

height of 10 m?

## Answers

Answer:600 J = 600 N m (newton meters)Explanation: To do this quickly, we should know that this question is asking us to how much work has been done on the object - and...because its falling from a height, we can switch this up to ask - "what is the change in potential energy of the object?" Which means that we can use this formular - PE = mgh where.....m = the mass of the object g = the accerlation due to gravity and...h = which is the height of the falling object. When we put that all together we get; PE = [tex]6kg(10m/s^{2})(10m)[/tex]Multiplying everything out gives 600 J or joules, which also equals 600 N m.
