Suppose a projectile is fired from a cannon with velocity vo and angle of elevation 0. The horizontal distance R (0) it travels (in feet) is given by the following. Español (vo) sin 20 R(0) = 32 If vo=160 ft/s, what angle 0 (in radians) should be used to hit a target on the ground 493 feet in front of the cannon? Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a radian. (If there is more than one answer, enter additional answers with the "or" button.) - 0 rad O or O
