1. Type III Projectile

2. Type III Projectiles
These projectiles are launched at an angle other than zero degrees (That’s a type ___) and they land at a different height than the launch height.
Examples of Type III:

3. Solving Type III Make a triangle to get vix and viy
Make X and Y charts
If you solve for t in the Y direction, it takes two steps
Impact velocity is found just like in Type I problems
Velocity at the zenith is just like in Type II
tup ≠ tdown
final speed ≠ initial speed
DO NOT USE DERIVED EQUATIONS YOU FIND IN THE TEXT!!!

4. Ex 1
A football is kicked at 20.0 m/s, at an angle of 50⁰ (above horizontal). What is the maximum range if the ball must clear a 3.05 m high bar?

5. POD
An Olympic diver leaves the 10.0m tall platform going 3.5m/s at a 60° angle. Determine the divers velocity (that means magnitude AND direction) when they impact the water.

6. Type III Performance Assessment
Part I: Fire your marble vertically to determine the magnitude of its initial velocity.
Part II: Ask instructor for a launch angle.
Part III: Determine range if launcher is on lab table, and target box is on floor.
Part IV: Test prediction
Part V: Write a two part word problem that includes all your measurements.
Part VI: Show the neat solution to the two part word problem.
Note: Part V must precede part VI on your report!

7. Assignments Quest! Phet Simulation: Lab (Tuesday)

Measure everything EXCEPT RANGE
On back of WS, solve for range
Position target and test
