1. Projectile motion Free-falling while moving horizontally Moving in two directions at the same time

2. Projectile motion

3. Parabolic trajectory Vertical motion: with acceleration of -9.8 m/s2 and initial velocity vy and vertical displacement Δy Horizontal motion: constantvx and horizontal displacement Δx

4. Projectile motion

5. An object launched horizontally

6. Find the initial speed of the bike

7. Lab – Launching a Projectile Horizontally • Work in pairs • Each person should have his / her set of data • Each student turns in a report with his / her name on it.

8. Projectile Launched at an angle Projectile has initial velocity in both directions

9. Example • A football is kicked 22 m/s at 40o to the horizontal. Calculate the maximum height and horizontal range the football will reach before it falls down (providing no one catches it).

10. 1st step:

11. Example 2 (p.110, #35) • A place kicker must kick a football from a point 36.0 m from the goal. As a result of the kick, the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 20.0 m/s at an angle of 53° to the horizontal. • a. By how much does the ball clear or fall short of clearing the crossbar? • b. Does the ball approach the crossbar while still rising or while falling?
