Amodel 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 58degrees. use the information to find how high the marble went and how fast the engine was moving.
