Homework Help: Physics

Posted by Elaine on Wednesday, September 19, 2012 at 8:51am.

Bob jumps from a 2.0 m high table and wants to jump over a 0.85 m radius ball. How fast must Bob move horizontally to not land on the ball?

If we use kinematics equations for projectile, the answer is 2.66 m/s; however, with this velocity the person will land on the ball. I need to find the velocity at which the person will just miss the ball. And I know this velocity is less than 5 m/s. Thank you for your help.
