The total kinetic energy of an object can be calculated using the formula KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity.
When the ball reaches its highest point, its velocity is 0 m/s because it has momentarily stopped moving in the upward direction. Therefore, the kinetic energy at the highest point is 0 Joules.
So the correct answer is:
A) 0 J
