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. (vo)² sin 20 R (0)= 32 If y=80 ft/s, what angle 0 (in radians) should be used to hit a target on the ground 112 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.) = rad 0= or x
