**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.
