1. Day 17 2-23-11 Topic: Projectile Motion
Objective: I will analyze the 2 components of projectiles.
Science starter: Next slide--

2. Two Golfers
Andy and Jan decide to hit golf balls off a cliff onto a flat pasture below. Both hit the balls horizontally. Andy hits his ball so it travels at a larger velocity than Jan’s. Whose ball hits the ground first? Whose ball hits the ground farther? Explain your reasoning.

3. Finding Horizontal and Vertical distance of a projectile
