Question1
An ocean liner leaves New York City and travels 32.0° north of east for 299 km. How far east and how far north has it gone? In other words, what are the magnitudes of the components of the ship's displacement vector in the following directions?
Question2
if an airplane propeller rotates at 2000 rev/min while the airplane flies at a speed of 480 km/h relative to the ground, what is the linear speed of the tip of the propeller, at radium 1.5 m as seen by
a) the pilot
b) an observer on the ground (the plane's velocity is parallel to the propeller's axis of rotation)
Question3
A train on one track moves in the same direction as a second train on the adjacent track. The first train, which is ahead of the second train and moves with a speed of 32 m/s, blows a horn whose frequency is 124 Hz. If the frequency heard on the second train is 135 Hz, what is its speed?
