Answer:

Mass = 100 kg

Acceleration due to gravity = 9.8m/s

Height = 10 m

Work done = mgh

= 100 x 9.8 x 10

= 9800 J

Hope this helps!

The work done by gravity on the object is 9800 Nm

Given the following data;

Also, we know that acceleration due to gravity is equal to 9.8 m/s^2.

To find the work done by gravity;

Mathematically, the work done by an object is calculated by using the formula;

[tex]Workdone = force * distance[/tex]

But, we would have to solve for the force acting on the object since it wasn't explicitly stated.

[tex]Force = Weight = mass * acceleration \;due\; to \;gravity[/tex]

[tex]Force = 100 * 9.8[/tex]

Force = 980 Newton

Now, we can solve for the work done by gravity on the object;

[tex]Workdone = 980 * 10[/tex]

Work done = 9800 Nm

Therefore, the work done by gravity on the object is 9800 Nm
