You are attempting to row across a stream in your rowboat. Your paddling speed relative to still water is 3.0 m/s (i. e., if you were to paddle in water without a current, you would move with a speed of 3.0 m/s ). You head off by rowing directly north, across the stream.
Assume that the stream flows east at 4.0 m/s, determine how far downstream of your starting point you will finally reach the opposite shore if the stream is 6.0 meters wide.

8 m

Explanation:

Vertical component of the speed of the boat = 3.0 m/s

horizontal  component of the boat = 4 m/s

the rowboat traveled the length of the river which = 6.0 m

time taken to travel across the 6 m wide river = 6 m / 3 m/s = 2 s

the distance far downstream of the starting point = horizontal speed × time = 4 m/s × 2 = 8 m

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
