A train is moving to the right at \(20\,\text{m/s}\). A passenger on the train throws a ball horizontally to the left at \(5\,\text{m/s}\) (relative to the train).(a) What is the velocity of the ball relative to the ground? , (b) How far does the ball travel relative to the ground in \(0.50\,\text{s}\)? , (c) The ball is thrown from a height of \(1.5\,\text{m}\) above the train floor. What is the velocity of the ball relative to the train when it hits the floor? :

\(15\,\text{m/s right}\) \(7.5\,\text{m}\) \(7.4\,\text{m/s at }47^{\circ}\text{ below left}\)
