A passenger on a moving train tosses a coin with an initial velocity of (-2.25 m/s) + 4.68 m/s) (from the point of view of the passenger). The train's velocity relative to the ground is (11.5 m/s).

(a) What is the minimum speed of the coin relative to the ground during its flight?
______m/s

(b) At what part in the coin's flight does this minimum speed occur?
-immediately after being tossed
-at some point as it is rising
-at the top of its motion
-at some point as it is falling
Explain.

(c)Find the initial speed and direction of the coin as seen by an observer on the ground.
____m/s
____° (counterclockwise from the +x axis)
(d) Use the expression for ymax derived in Example 4-7 to calculate the maximum height of the coin, as seen by an observer on the ground.
____m

(e) Repeat part (d) from the point of view of the passenger.
____m
