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 into the air along a path that he judges to make an initial angle of 60.0 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 she see the ball rise?

  • Physics - ,

    The vertical initial Velocity component is
    Vyo = 10 sin60 = 8.66 m/s
    in either coordinate system.

    The ball will rise a distance H given by

    g H = (1/2) Vyo^2 = 3.82 m

    Thank you...
