Troyanec [42]3 years ago
5 0

Answer:

<h2>20 kg</h2>

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

<h3>20 kg</h3>

madam [21]
