Nikolay [14]

Answer:

m=30.581kg

<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>

Assuming this is happening on earth, acceleration due to gravity (g) is 9.81m/s/s.

Force of gravity is the acceleration due to gravity multiplied by its mass:

F=mg

300=(9.81)m

m=30.581kg

<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>
