A rifle is firmly attached to a heavy bench, with its 75.0 cm long barrel pointing horizontally. It fires a 9.00 g bullet which leaves the muzzle at a speed of 970 m/s. assuming the acceleration of the bullet down the length of the barrel to be constant, what horizontal force does the gun exert on the bench as it fires?
