The range r of a projectile is given by r= v sin 20, where v is the initial velocity and 0 is the angle of elevation. If r is to be 3,000 ft 32 and v = 3,000 ft/ sec, what must the angle of elevation be? Give an answer in degrees to the nearest hundredth. .... O A. 0.31° B. 0.43° O C. 89.69° O D. 0.61°
