Answer: 3.92 joules

Explanation:

Mechanical energy is the sum of energy possessed by a body during motion and at rest. It is measured in joules

M. E = Mass x Acceleration due to gravity x height

Now, since mass of ball = 0.200-kilogram Height = 2.00 meters from the floor

Recall Acceleration due to gravity (g) is 9.8m/s^2

Then, M. E = mgh

= 0.2 x 9.8 x 2.0

= 3.92 joules

Thus, the mechanical energy of the ball is 3.92 joules
