**Motion in Two Dimensions**

Projectiles

2
Projectiles Under the influence of gravity alone, near the Earth’s surface an object accelerates downward at 9.8 m/s2. This acceleration is vertical and does not affect the horizontal velocity.

**Conceptual Example 5 I Shot a Bullet into the Air... **

3.3 Projectile Motion Conceptual Example 5 I Shot a Bullet into the Air... Suppose you are driving a convertible with the top down. The car is moving to the right at constant velocity. You point a rifle straight up into the air and fire it. In the absence of air resistance, where would the bullet land – behind you, ahead of you, or in the barrel of the rifle?

**Example 6 The Height of a Kickoff **

3.3 Projectile Motion Example 6 The Height of a Kickoff A placekicker kicks a football at and angle of 40.0 degrees and the initial speed of the ball is 22 m/s. Ignoring air resistance, determine the maximum height that the ball attains.
