Q. A science student is riding on a flatcar of a train travelling along a straight, horizontal track at a steady speed of 11.00 m/s. The student throws a ball into the air along a path that he judges to make an initial angle of 59° with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes ball to rise vertically. How high does she see the ball rise?
