A trajectory of a fighter plane is given...

A trajectory of a fighter plane is given by the relation y = x + c (when and y represents horizontal and vertical axes). The plane is moving with a constant speed of `30sqrt2 m//s`. A machine gun is mounted on the plane. When the plane is at a height of 240m from the ground, a bullet is fired from the machine-gun with a speed of 10 m/s with respect to the plane in the vertical upward direction.
(a) Calculate the time after which it will hit the ground
(b) Find the maximum height reached by the bullet.
