... 45. If the total energy of an object of a falling object was 100 J just before it was dropped, and it had a K.E of 80 J just before it hit the ground, what was the work done by air resistance on it ? 46. What is the work energy theorem ? How do you use it to calculate the change in K.E. of an objec ...
