Question

1) Harold pushed a 10 kg box to the right with 7 Newtons of force. Jerome pulled the same box to the right with 7 Newtons of force. Are the forces on the box balanced? Will the box accelerate?

Answer 1

Given data:

mass of box = 10 kg,

Force (F1) = 7 N, (push towards rightside)

Force (F2) = 7 N (Pulled towards right side)

It is clear from the question that the two forces are acting in the same direction, so the box will accelerates.

Total force(F) = 7+7 = 14N.

According to Newtons II law F=m.a

                                                 14   = 10 × a

                                                     a = 1.4 m/s2

The box accelerates with 1.4 m/s2
