Answer to Question #156548 in Physics for buddy

Question

A man lifts a heavy box that weighs 121 N into the air. If the net force on the box is 6.0 N upward, what is the magnitude of the lifting force that the man puts on the box?

Answer 1

The lift force can be found as follows:

$$F_{net}=F_{lift}-W,$$ $$F_{lift}=F_{net}+W=6\ N+121\ N=127\ N.$$

Answer:

$F_{lift}=127\ N.$
