Referring to 73, suppose the initial velocity of the coin
Chapter 4, Problem 89(choose chapter or problem)
Referring to 73, suppose the initial velocity of the coin tossed by the passenger is . The trains velocity relative to the ground is still .(a)What is the minimum speed of the coin relative to the ground during its ight? At what point in the coins ight does this minimum speed occur? Explain. (b) Find the initial speed and direction of the coin as seen by an observer on the ground. (c) Use the expression for derived in Example 47 to calculate the maximum height of the coin, as seen by an observer on the ground. (d)Repeat part (c) from the point of view of the passenger. Verify that both observers calculate the same maximum height.
