Medal

A 6-newton object is raised 12 meters. How much work is done?



2 newton-meters

72 foot-pounds

72 newton-meters

Answer 1

Work is energy. What we have here is gravitational potential energy, that is:
\[U = mgh\], m is the mass of the object, g is gravity and h is the hight

Answer 2

The weight of a object is \(w = mg\), so \(U = wh\), you have w and h, now calculate the work
