Two men move identical heavy boxes, the same distances across a horizontal rough floor as shown. First man is pushing his box, while the second is pulling on his box with a force of same magnitude as shown in the figure. Which one of the following represents correct statements ?
Options:(select one or more)
Answer:
A, C
Solution:
Work by each man with equal F, d and angle - equal work (A).
Pushing increases the normal, hence friction, so the first man moves slower and takes longer; same work over more time means less power. The second man delivers more power - (C).
