This is from EK 1001 for physics, #254:
A man holds one end of a 30 cm spring in each hand. If he applies a 100N force to each end of the spring, by how much does he shorten the spring? k=1000N/m
The answer is 10cm...the explanation goes on to say that the length of the spring is irrelevant.
Well...I know that length is irrelevant, but wouldn't the answer be 20 cm since he's applying the force with each hand?????
