A 700 gram ball is thrown from the top of a 25 meter tall building. The ball is thrown with an initial speed of 10 m/s at an angle 30 degrees above the horizontal. For our conservation of energy calculations, we will choose the Ball + Earth as our system and use the ground as h = 0.
The kinetic energy of the ball when it is thrown =   J.

When the ball reaches its highest point the kinetic energy is NOT zero. At the highest point the ball's kinetic energy =   J.

At the highest point, the gravitational potential energy =   J.

The maximum height the ball reaches =   m above the ground.

When the ball reaches the ground, its speed =   m/s.
