TAB 4 "Lab": In this part you will actually calculate the range and compare to the on-screen data. Launch the cannonball from ground level at 15 m/s at 37 degrees (without air resistance). Draw a vector diagram and calculate the x- and y- components of Vi. Use Viy=gt; R = Vxt; H = 1/2gt? to calculate the time, height and range of the projectile. Show all your calculations. Vix = Viy = t = H = R = Do the results from your calculations match with the values you find using the cross-hair instrument
