1. Non-Horizontally Launched Projectiles 11/12/2013

2. The details of motion in each direction have not changed.

3. The parabolic path of the object is altered slightly due to a change in the initial vertical velocity (viy).

4. Consider the following diagrams when answering the questions. 2 1 3 4 5 • Which diagram might represent horizontal velocity? • Which diagram might represent vertical velocity? • Which diagram might represent horizontal acceleration? • Which diagram might represent vertical acceleration? • Which diagram might represent the net force?

5. Suppose a rescue airplane drops a relief package while it is moving with a constant horizontal velocity at an elevated height. Assuming no air resistance, where would the package land?

6. Horizontal and Vertical Components of Velocity. A cannonball is launched 15 degrees above the horizontal at 75.7 m/s. What are the vertical and horizontal components of it’s velocity? θ

7. Horizontal Component of Velocity

8. Vertical Component of Velocity How does this change in initial vertical velocity affect the calculation of free fall?

9. Complete the following chart for this scenario.

10. Lets compare the displacement of a horizontally launched projectile with the displacement of a non-horizontally launched projectile.

11. Do both of these equations still apply?

12. Let’s practice using these equations. The diagram below shows the trajectory for a projectile launched NON-horizontally. The initial vertical and horizontal components are given. Complete the chart given for the scenario.
