Projectile Motion continued

During today's class we went over the ivory booklet pages 10, 15,17,18,23, and 24.
On page 10: Tossed Ball Problem
The answers are as follows:
20 m/s
10 m/s
5 m/s
5 m/s
11.2 m/s
20.6 m/s
30.3 m/s

The Trajectory of a Projectile
1. the highest point of the projectile has the smallest magnitude because ate this point vertical velocity equals zero.
2. their the same in magnitude but different in directions.
3. their the same in magnitude and directions.
4.

Vertical and Horizontal Projectiles
1. they are the same
2. they are the same
3. the horizontal motion does not affect the vertical motion
4. it is because of the vertical spacing between the ball's motion is changing
5. it's because the horizontal distance between the red ball's motion are the same
