A cannon shell is launched with an initial velocity of 387 m/s at an angle of 15 º above the horizontal. Neglecting air resistance, determine the maximum horizontal displacement (Range) of the projectile in kilometers. Take the acceleration due to gravity as 9.8 m/s2. Please round your answer to one decimal place.
