Homework Help: Physics

Posted by Eddy on Sunday, April 18, 2010 at 5:18am.

Please help me... :(

There is a moving bowling ball on the track. A student says, "After the ball is thrown horizontally on the wooden track with horizontal velocity v and zero angular velocity, the translational kinetic energy of the ball remains unchanged before it hits the pins since the track is frictionless." Is this statement true or false, and why?

Another student asserts that the momentum of the bowling ball and the pins is conserved during the collision of the ball and the pins. What assumptions and conditions required for making such a comment?

If a bowling ball of greater mass is used instead, what will be the difference in the effect on the collision between the bowling ball and the pins?

I am really desperate for help... Thanks in advance.
