Physics Question! Please help I've been stuck on this for hours. ?
(STORY) You are riding a train to school. since the train car is almost empty, you and your friend are throwing a ball back and forth. the train is moving at a velocity of 5.6 m/s. suppose you throw the ball to each other at the same speed, 2.4 m/s
Questions: 1. What is the velocity of the ball relative to the tracks when the ball is moving forward to the front of the car?
2. What is the velocity of the ball relative to the tracks when it is moving towards the back of the car?
3. What if you and your friend throw perpendicular into the aisle of the train? What is the ball's velocity then?

(1) 8.0 m/s.
(2) 3.2 m/s.
(3) The velocity of the ball relative to the ground is
sqrt(2.4^2 + 5.6^2) = around 6 m/s but use a calculator.
