A military gun is mounted on a railroad car (m = 1590 kg) as shown in Figure P7.34. There is no frictional force on the car, the track is horizontal, and the car is initially at rest. The gun then fires a shell of mass 26 kg with a velocity of 280 m/s at an angle of 28° with respect to the horizontal. Find the recoil velocity of the car.
