Part 1: Velocity and Acceleration In this, you will gather data from a projectile and make graphs of position and velocity vs time in the x and y directions. If a projectile is launched with an initial speed of 10 m/s at an angle of 20, what is the x-component of the velocity? 1. Predicted vx = ___________ Go to https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html and click Intro. Leave the cannon at 10 meters high. Change the initial speed to 10 m/s, drag the cannon so it points at 20 degrees, and click to launch a pumpkin. What do you expect the x-component of velocity to be? Calculate it and show your work, including the initial equation. Move the crosshair of this tool over every other point and record your data in the table. Record the time, range (x-position), and height (y-position) of the pumpkin at every other point along the path. Then calculate the x and y components of the velocity. Remember that the average velocity during a time interval is the same as the instantaneous velocity at the halfway point. I filled in the first data points for you. Make sure you get the same result before filling in the rest. Fill the table with entries like shown below:
