Math concepts • Shot Speed • Position of a shot • Bounce shot
The Lacrosse Ball • solid rubber ball • between 7.75 and 8 inches (19–20 cm) in circumference • (about 2.5 inches (6.5 cm) in diameter) • weighs between 5 and 5.25 ounces (140–150 g).
Shot Speed • Record shot speeds exceed 120 mph • dr/dt= 120 mph
Angles of a bounce shot • The way to get a perfect bounce shot all depends on the angle of the shot and the distance away from the goal.
How to Calculate a Bounce Shot ? A • How to make the ball to point A on the goal. But were would point B, be!?! B
Similar Triangles • If ball bounces half way. It'll go in at the same height as it was released.
