Projectile Motion
2
Projectiles follow parabolic paths!
3
How does air resistance effect the trajectory?
4
How does gravity effect the trajectory?
5
How does angle effect the trajectory?
6
Different types of trajectories and components.
7
Projectile motion is free fall with an initial
horizontal velocity!

Projectile Motion Example 1

• The Royal Gorge Bridge in Colorado rises 321 m
  above the Arkansas River. Suppose you kick a
  rock horizontally off the bridge. The magnitude
  of the rocks horizontal displacement is 45.0 m.
  
• (a) Find the speed at which the rock was kicked.
• (b) Total time of flight.
• (C) Velocity of projectile at the ground.

Example 2
A ball is thrown with an initial velocity Of 100
ft/s at an angle of 60º. Find (a)Maximum
height of ball. (b)Time to the top. (c)Total time
of flight. (d)Range of the ball. (e)Velocity of
ball as it strikes ground. (f)Position and
velocity of ball at t4s.

Example 3

• A projectile is fired from the top of a
• Building at an initial velocity of 35 m/s
• Upward. The top of the building is 30m
• Above the ground.
• Find
• Maximum height.
• Time to the top.
• Velocity as objects strikes the ground.
• Total time projectile is in the air.

Example 4
A projectile is fired at an initial velocity Of
35 m/s at an angle of 30º from the Roof of a
building 30 m high. Find (a)Maximum
height. (b)Time to top. (c)Time of
flight. (d)Velocity of object at ground. (e)Range
of the projectile.

Example 5
A basketball player shoots a ball with an initial
velocity of 10 m/s at an angle of 60º form a
height of 1.8 m. The height of the basket is 3.0
m. Find (a)Time to top. (b)Maximum height from
floor. (c)Time to fall to basket. (d)Distance of
shot from basket.
