Question

a 25 kg object is pushed with a horizontal force of 5 N esat across a table. If the force of friction is 2 N, what is the acceleration of the object?

Answer 1

Apply Newton's second law in the moving direction.

Step-by-step explanation:

`\begin{aligned}F &= ma\\5N-2N &= 25kg* a\\a & = (3N)/(25kg)\\&= 0.12ms^(-2)\end{aligned}`

Friction force applies in the opposite direction of motion; as a restriction.
