Question

A model train engine was moving at a constant speed on a straight horizontal track. As the engine moved​ along, a marble was fired into the air by a spring in the​ engine's smokestack. The​ marble, which continued to move with the same forward speed as the​ engine, rejoined the engine 1 sec after it was fired. The measure of the angle the​ marble's path made with the horizontal was 46°. Use the information to find how high the marble went and how fast the engine was moving.
