Exams tomorow! please help
A billiard ball is hit with a horizontal force F. The force hits the ball with the height h over the ball's center. the initial velocity is v0 and the the velocity afterward is (9/7)v0. Show that the height h is (4/5)R, where R is the radii of the ball.
Newtons second law: Fdt=mdv
momentum: t=r x F=Iw
I don't really understand this. please help. Thank you very much
