The range of a projectile that lands at the same height from which it was launched can be derived from the equations of kinematics with constant acceleration: R = (2v2/g) sin 0 cos 0. Based on this equation, for any given angle 0 (where 0 is between 0 to 90 ), what second angle will have the same range? (Assume the projectile has the same initial velocity.) Select one: O a. 180- 8 O b. 120- 8 O c. 90 - 0 O d. 60- 8
