Question

A mass m1 = 5.7 kg rests on a frictionless table and connected by a massless string to another mass m2 = 3.9 kg. A force of magnitude F = 37.0 N pulls m1 to the left a distance d = 0.77 m. How much work is done by the force F on the two block system in J and how much work is done by the normal force on m1 and m2?

A mass m1 = 5.7 kg rests on a frictionless table and connected by a massless string to another mass m2 = 3.9 kg. A force of magnitude F = 37.0 N pulls m1 to the left a distance d = 0.77 m. How much work is done by the force F on the two block system in J and how much work is done by the normal force on m1 and m2?

Explanation / Answer

a) W = F d cos theta = 37*0.77=28.49 J b) W = N d cos theta = N d cos 90 = 0 J
