Figure A1.5 is obtained by recording the bounce of a golf ball with mass m = 0.016 kg using a high- speed video camera. At position ho, the ball's velocity has only a horizontal component Vox as shown and no vertical component. After the ball impacts the ground, it reaches height h1 = 0.65 ho.

What can be said about the magnitude of the horizontal velocity Vox as a function of time and position if ideal projectile motion theory is applied? What is the basic assumption of ideal projectile motion theory?
What is the coefficient of restitution, e, between the ball and the ground?
What does your result imply regarding the ratio between angles 0 and 02 before and after the ball impacts the ground? Derive a relationship between angles 0 and 2 which can be used to confirm and quantify your statement.
