If it take 150 N of force to move a box 10 meters what is the work done on the box?

Description : If it take 150 N of force to move a box 10 meters what is the work done on the box?

Last Answer : Work = Force x DistanceWhen multiplying by 10 you simply shift all the digits to the left and append a 0 to the end.so 150 x 10 = 1500 JoulesExtra CreditThe Joule is defined as the amount ... meter.This kind of question is easier to answer if you learn the descriptive definitions for the SI units.
