I need to find the angle of projection for the maximum range. I have the following information: angle (degrees) and average range (cm). Here are two angles and the range for each. Angle              Average Range (cm) 10                         146.5 45                         272.5   I think that I use this formula but I am not for sure. R=(V20 sin 2 theta)/g   Can you help me figure this out so that I can do the rest of the angles and ranges.
