Answer: 33.7kg
Explanation:
Using Newton's 2nd Law, the force of gravity is equal to the mass times the acceleration:
[tex]F=ma[/tex]
The force would be the weight due to the gravitational field. And the acceleration would be the one due to gravity:
[tex]330N=m(9.8m/s^2)[/tex]
[tex]m=330/9.8[/tex]
[tex]m=33.7kg[/tex]
