A gun is mounted on a trolley which is being pulled by a car travelling on the same road away from the gun with a uniform speed of 72√2 km/h. The car is at a distance of 50 m from the gun when the gun is fired at an angle of 45° with the horizontal. Find the distance of the car from the gun when the shell hits it, and the speed of projection of the shell. Take g = 10 m/s². Find the speed of projection of the shell (m/s).
