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.

A ball is projected from a point in a horizontal plane so as to strike a vertical wall at right angle A .after rebounding from the wall it strikes the horizontal plane once and returns to the point of projection just before second collision at horizontal surface. Find co-efficient of restitution for the two collisions, assuming it to be same for both the collision.
