DATA:

                  u = 2.05 km/s

                  Angle = 71.7

Solution:

                 Now as we know the formula for horizontal distance

                R = u^2 sin( 2 theta) / g 

                R = (2.05)^2 sin( 2 (71.7)) / 9.8

                R = (4.2025) sin(143.4) / 9.8

                R = (4.2025) (0.5962) / 9.8

                R = (2.5055305) / 9.8

                R = 0.256 km
