Answer:

Explanation:

Y = a x - b x^2

Range is a/b

y = tan Ф x -  g x²  / 2 u² cos² Ф

tan Ф = a        -  equation 1

b = g / 2u² cos² Ф          so  u² cos² Ф = g /2b    - equation 2

R = u cos Ф * 2 * u sin Ф / g  = 2/g  sinФ  u² cos Ф

    = 2 /g   tan Ф   u² cos² Ф            by using equation 1  and equation 2

    = (2 /g )  a  (g / 2b ) = a / b
