Answer :
Final answer:
The work done on the mass is 9000.0 Joules.
Explanation:
The work done on an object can be calculated using the formula:
Work = Force x Distance
In this case, the horizontal force applied is 300.0 N and the distance is 30.0 m. Plugging these values into the formula:
Work = 300.0 N x 30.0 m = 9000.0 J
So, the work done on the mass is 9000.0 Joules.
