A diwali rocket moves vertically up with a constant acceleration `a_(1) =20`//` 3 m s^(-2)`. After sometives, its fuel gers exhausted ad then if falls freely with an acceleration `a_(2) =10 m s^(-2)`, If themaximum height attained by the diwalin rocket is (h), using graphicalmerhod, find its speed when the fuel is just exausted. Assume `h=50 m`.
