Zero

Explanation:

It really has to do with the reference point of where the ball is and where the ground is.

Taking what we have here we can use the equation
PE=mgh
And plug in the numbers for mass gravity and the height
PE=(3.0)(9.81)(0m)
The zero height means that the ball has no potential energy.

No potential energy or 0 joules.

Explanation:

Potential energy is given by the equation,

"PE"=mgh

  • m is the mass of the ball in kilograms

  • g is the gravitational acceleration, which is 9.8 \ "m/s"^2

  • h is the height of the platform the ball is standing on

So, here, h=0, and so, we get:

"PE"=m*g*0

=0

In conclusion, the ball has no potential energy.
