Calculating heat energy...
Q. #1
A 16 kg object is dropped from a height of 25 m and strikes the ground with a speed of 18 m/s. How much heat energy was produced during the fall?
Choices
A) 0 J
B) 2 600 J
C) 1 300 J
D) 3 900 J
Well,according to my calculation, the average acceleration was about 6.48m/s, which means 3.32N/kg acted as air friction.
And I'm lost from there.
Help will be greatly appreciated!
