vo 0 R Fig.10.14 The range R of a projectile varies jointly as the square of its ini- tial volocity 1 and the sine of twice the angle o from the hori- zontal at which it is fired. See Fig. 18.14. A bullet for which 850 m/s and 0 - 22.0° has a range of 5.12 x 104 m. Find the range if v - 750 m/s and 6 - 43.2º. m/s
