Set-up: Set initial speed at 15 m/s. Set the height of the cannon to 0 meters. Be sure that air resistance is NOT checked. B. 2. Our independent variable in this simulation will be the launch angle. Keeping the speed at 15 m/s, vary the launch angle as indicated in the table below. Drag the crosshairs marked with time and range to the spot where the object landed. Then drag the crosshairs to the top of the parabola to find max height. Fill in the table below with the values.
