25 N 3 kg
10 N
A 25 N force pushes on one side of a box while a 10 N force pushed on the other as shown in the diagram above. If the box has a mass of 3 kg, what
acceleration should we expect and in what direction (L = to the Left... R = to the Right)?
O 5 m/sec2 to the Left
O 11.67 m/sec2 to the Left
O 5 m/sec2 to the Right
O 11.67 m/sec2 to the Right

Motivation cannot be developed with practice; a person either possesses it or they do not.
