Question: An golf ball sits on the optical axis of a spherical mirror at a distance of 17 cm. A virtual image is formed a distance of 6 cm away from the mirror. What is the mirror's focal length (include sign if negative)?
The initial angle of the ball’s motion off the tee is 29.0° above the horizontal. If the tee level is 17.0 m above the level of the fairway, explain how far east of the tee does the ball hit the fairway?
