1. What is projectile motion? 2. Find the initial velocity, vo, of a ball rolling off the table in the figure below. The launch position is the origin of the coordinate system, positive directions as specified. + y + X 0.8 m O 1.1 m3. Using the table height and launch speed from the previous question, predict the final landing distance in the x direction if the launcher is adjusted to an angle of 40.Objective: The objective of this lab is to investigate projectile motion, first when a projectile is fired horizontally, and then when a projectile is fired from a non-zero angle of elevation. PROCEDURE Part 1: Horizontal Launch (60 = 0") 1. Open the Projectile Motion simulation in your browser and select the "Lab" option. Ensure gravity is set to 9.80 m/s and the " air resistance" box is unmarked. 2. Set the initial height of the object as 5m by clicking and dragging the crosshairs at the back of the cannon. 3. Set the launch angle to 0" by clicking and dragging the front of the cannon. 4. Choose the origin of your coordinate system. You will need to decide whether the origin is at the launch position or at the ground. and which direction is positive and which is negative. Record your decision below: (5 points) 5. Set the initial launch velocity to 10 m/s by clicking the arrows or dragging the slider under "Initial Speed". 6. Predict the time of flight and landing position using the kinematic equations and record them in the table on the next page (x(m) (calc) and t(s) cale) ), show your work here. (15 points)
