A science student is riding on a flatcar of a train traveling along a straigh, horizontal track at a constanst speed of 10m/s. The student throws a ball into the air along a path that he judges to make an initial angle of 60 degrees with the horizontal and to be in line with the track. The student's professor who is standing on the ground nearby observes the ball to rise vertically. How high does he see the ball rise?
