Jonathan is pushing a 25 kg box with a force of 135 N. The overall net force for the box is 70 N. Using this information, calculate the magnitude of the frictional force on the box.

Answer :

The magnitude of the frictional force of the box is 65 N

From the question given above, the following data were obtained:

  • Mass (m) = 25 Kg
  • Force applied (Fₐ) = 135 N
  • Net force (Fₙ) = 70 N
  • Frictional force (Fբ) =?

The frictional force acting on the box can be obtained as follow:

Fₙ = Fₐ – Fբ

70 = 135 – Fբ

Collect like terms

70 – 135 = – Fբ

–65 = –Fբ

Multiply through by –1

Fբ = 65 N

Thus, the frictional force of the box is 65 N
