SHORT TEST

A swimmer is crossing a river with a width of L = 1 km, moving from one bank to the other perpendicular to the current at a constant velocity v = 4 km/h. The current velocity is = 2 km/h.

-          What do these two velocities represent?, Write their analytical expressions in the Cartesian coordinate system (xoy).

-          Calculate the angle at which the swimmer deviates.

-          Determine the swimmer's trajectory, velocity, and the time required to reach the opposite bank.
