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 [...]
