In a lake, two boats A and B are leaving Station1 at the same time, Boat A is directed straight to Station 2 at a constant velocity of 7m/s, while Boat B is travelling in the North- West direction (N45°W). It takes Bost A one and half minute (90 seconds) to reach Station 2. Station 2 is located to the west 315m south of Station 1. a. What is the velocity of Boat B if it appears to a person inside it that Boat A is moving at rate of 8m/s? b. At the instant when Boat A reaches Station 2, what is the relative position (magnitude and direction) of Boat B with respect to A? -Boat B Stetion 1 Boat/A 7 m/s 315 m Station 2.

Question
– EVEN:
In a lake, two boats A and B are leaving Station1 at the same time, Boat A is directed
straight to Station 2 at a constant velocity of 7m/s, while Boat B is travelling in the NorthWest direction (N450W). It takes Bost A one and half minute (90 seconds) to reach
Station 2. Station 2 is located to the west 315m south of Station 1.
a. What is the velocity of Boat B if it appears to a person inside it that Boat A is moving
at rate of 8m/s?
b. At the instant when Boat A reaches Station 2, what is the relative position
(magnitude and direction) of Boat B with respect to A?
