A 0.150kg baseball is thrown upwards with an initial speed of 20.0 m/s. What is the force on the ball when it reaches half its maximum height? (Disregard air resistance.) What is the force on the ball when it reaches its peak?

The force on the ball is gravitational weight, that what makes is slow down going up, and speed up when it falls.
