Homework Help: HS Physics

Posted by Tzana on Friday, October 15, 2010 at 6:22pm.

Please help...I know the direction is up, but I can't figure out the magnitude, except that its label is kg m/s, I think.

A 0.400-kg ball is dropped from rest at a point 1.80 m above the floor. The ball rebounds straight upward to a height of 0.730 m. What are the magnitude and direction of the impulse of the net force applied to the ball during the collision with the floor?
