Question

If 400 N of force was applied to a rock and it had an acceleration of 20 ms2 , what is the mass of rock?

Answer 1

Answer:

20 kg

Explanation:

The mass of the rock can be found by using the formula

$m = \frac{f}{a}$

f is the force

a is the acceleration

From the question we have

$m = \frac{400}{20} = \frac{40}{2}$

We have the final answer as

20 kg

Hope this helps you
