1. If a plane flies at 4.5 x 102 km/h against a 3.2 x 102 km/h wind, how long does it
take the plane to fly between two stations that are 300 km apart?
2. A person runs from the front to the back of an aircraft at a velocity of 3.0 m/s. IF
the aircraft carrier is moving forward at 20.0 m/s, how fast does the spy appear to
be running when viewed by an observer on a stationary submarine?
3. Suppose a dolphin begins to chase a fish at 37.0 km/h when the fish is 50.0 m
away. The fish swims away at a speed of 15.0 km/h. How long would it take the
dolphin to catch the fish?
4, an animal transport moves at 30.0 m/s north along a highway. Inside a dog moves
at 2.00 m/s at an angle of 45° east of north. What is the velocity of the dog relative
to the road?
