To determine: The velocities of the swimmer with respect to the current when the boy swims directly upstream and directly downstream.
Answer to Problem 1IP
The velocities of the swimmer with respect to the current when the boy swims directly upstream and directly downstream are 2 m/s in the upstream and 1 m/s in the downstream.
Explanation of Solution
Calculation:
The velocity of the swimmer with respect to the current when the boy swims directly upstream is,
Here,
Substitute
Thus, the velocity of the swimmer with respect to the current when the boy swims directly upstream is 2 m/s.
The velocity of the swimmer with respect to the current when the boy swims directly downstream is,
Here,
Substitute
Thus, the velocity of the swimmer with respect to the current when the boy swims directly downstream is 2 m/s.
Therefore, the velocities of the swimmer with respect to the current when the boy swims directly upstream and directly downstream are 2 m/s in the upstream and 1 m/s in the downstream.
