Question

1. Two men, Joel and Jerry, push against a wall. Jerry stopsafter 10min, while Joel is able to push for 5 min longer. Comparethe work they do: a.) Joel does 50% more work than Jerry b.) Jerry does 50% more work than Joel c.) Joel dos 75% more work than Jerry d.) Neither of them do any work 2. Matthew pulls his little sister Sarah in a sled on an icysurface (assume no friction), with a force of 60N at an angle of 37degrees upward from the horizontal. If he pulls her a distance of12m, the work he does is: a.) 185J b.) 433J c.) 575J d.) 720J Could you please show your work, if possible. 1. Two men, Joel and Jerry, push against a wall.

Explanation / Answer

1. Neither of them do any work since W=Fd and a force is appliedbut it doesn't create any distance between them and the wall. 2. W=FdCos=(60N)(12m)Cos37=575.017 Joules
