A projectile is fired at 0=420.0 m/s at an angle of theta=63.6∘ , with respect to the horizontal. Assume that air friction will shorten the range by 30.1% . How far will the projectile travel in the horizontal direction, ? Parabolic trajectory with an initial velocity V subscript 0 that makes an angle theta with the ground. The horizontal distance is labeled R. distance traveled:
