Homework Statement
A 0.04-kg ball is thrown from the top of a 30-m tall building (point A) at an unknown angle above the horizontal. As shown in the figure, the ball attains a maximum height of 10 m above the top of the building before striking the ground at point B. If air resistance is negligible, what is the value of the kinetic energy of the ball at B minus the kinetic energy of the ball
at A , that is calculate (K(B) – K(A))?

The Attempt at a Solution
I think K(B)- K(A)=K(B)=mgh is this correct?
