Two forces of 10 n and 30 n are applied to a 10 kg box. find (1) the box’s acceleration when both forces point due east and (2) the box’s acceleration when 10 n force points due east and 30 n force points due west.

Explanation:

Given that,

First force = 10 N

Second force = 30 N

Mass of box = 10 kg

(1). When both forces point due east

Then the net force will be

We need to calculate the acceleration

Using newton's second law

put the value into the formula

The box accelerate towards east.

(2). When 10 N force points due east and 30 N force points due west.

Then the net force will be

We need to calculate the acceleration

Using newton's second law

The box accelerate towards west.

Hence, This is the required solution.
