A science student is riding on a flatcar of a train travelling along a straight horizontal track at a constant speed of 10.0 m/s.The student throws a ball along a bath that she judges to make aninitial angle of 60.0 degrees with the horizontal and to be in linewith the track. The student's professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does the ball rise?need to see step by step.
