Question

A UPS delivery man lifts a package of 250 N of force in lives at 2 m off the ground. How much work did he do

Answer 1

Work = Force x distance

Force = 250 N

distance = 2 m

Replacing with the values given:

W = 250 N x 2 m = 250 kg m / s^2 x 2m = 500 kgm^2/s^2 = 500 J

1 N = 1 kgm/s^2

1J= 1 kg m^2 /s^2
