A 0.155 kg baseball is thrown upward with an initial speed of 14.5 m/s.
What is the force on the ball when it reaches half of its maximum height? (Disregard friction.)
What is the force on the ball when it reaches its peak?
M*g = 1.52 Newtons (the weight), in both cases. I assume the ball is thrown on Earth somewhere. That is why the g comes in.
