Non-Horizontally Launched Projectiles. 11/12/2013. The details of motion in each direction have not changed. The parabolic path of the object is altered slightly due to a change in the initial vertical velocity ( v iy ). Consider the following diagrams when answering the questions. 2. 1. 3.

Non-Horizontally Launched Projectiles 11/12/2013
The parabolic path of the object is altered slightly due to a change in the initial vertical velocity (viy).
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?
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?
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
Vertical Component of Velocity How does this change in initial vertical velocity affect the calculation of free fall?
Lets compare the displacement of a horizontally launched projectile with the displacement of a non-horizontally launched projectile.
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.
