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

20 kg

Step-by-step explanation:

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

`m = (f)/(a) \\`

f is the force

a is the acceleration

From the question we have

`m = (400)/(20) = (40)/(2) \\`

We have the final answer as

20 kg

Hope this helps you
