Question

Jeff pushes a 20kg box with a force of 150 newtons to the right while Jerry pushes the same box with a force of 80 Newtons to the left. The force of friction on the box is found to have a magnitude of 25 Newtons. What is the accelerations of the box?

Explanation / Answer

According to newtons second law

Fnet = m a

Fjeff - Fjerry - Ffriction = ma

150-80-25 = 20 a

a = 2.25 m/s2
