Homework Help: motion and force

Posted by PJ on Saturday, January 27, 2007 at 12:10am.

Consider a ball after it is thrown and going upward. The force on the ball is a). the force of gravity or b). some values between the force of gravity and the force of throw. What is the acceleration and what is the values of the acceleration. Explain your answer.

The acceleration is always g (downwards) and the force of gravity (called "weight") is M g. You should look up the value of g.

The "force of the throw" ceases when the ball is released.
