A spring-loaded cannon aimed at 41 o above the horizontal is on the last car of a long train of flat cars. The train has an initial velocity of 57 km/h. At the moment the train begins to accelerate forward at 0.345 m/s2 the cannon fires a projectile at 182 m/s. The cannon points in the direction that the train is moving. What is the horizontal range observed by a person standing on the ground?
