1. Chapter 3: Projectile Motion

2. Gravity, being a downward force, causes a projectile to accelerate in the downward direction.
The force of gravity could never alter the horizontal velocity of an object since perpendicular components of motion are independent of each other;
vertical force does not effect a horizontal motion.

3. The result of a vertical force acting upon a horizontally-moving object is to cause the object to deviate from its otherwise linear path

8. Projectile Motion

9. Practice Problems pp
Calculate the resultant velocity of Freda Flyer who normally flies at 100 km/h and then encounters a 10-km/h headwind(wind coming from ahead).
2. Calculate Freda Flyer’s speed in a km/h tailwind(wind coming from behind).

10. The Truck and The Ball
Imagine a pickup truck moving with a constant speed along a city street.
In the course of its motion, a ball is projected straight upwards by a launcher located in the bed of the truck.
What will be the path of the ball and where will it be located with respect to the pickup truck?

11. Practice Problems pp
12. A plane is flying at an altitude of 8000 m at a sped of 250 m/s. At what horizontal distance ahead of its target must a water balloon be released to strike the target on the ground(neglecting air resistance)?
