An objec with a mass of 7 kg accelerates 5m/s2 when an unknown force is applied to it. what is the magnitude of the unknown force?

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 7 × 5

We have the final answer as

Hope this helps you
