A juggler traveling in a train on level track throws a ball straight up, relative to the train, with a speed of 6.65 m/s. The train has a velocity of 19 m/s due east.
(a)
iend standing on the ground next to the track, what is the ball's initial speed? What is the angle of the launch?
(c) What is the displacement of the ball during its rise?
