Aman at point a directs his rowboat due north toward point b, straight across a river of width 100 m. the river current is due east. the man starts across, rowing steadily at 0.75 m/s and reaches the other side of the river at point c, 150 m downstream from his starting point. while the man is crossing the river, what is his velocity relative to the shore?

1.35208 m/s

Explanation:

Speed of the boat = 0.75 m/s

Distance between the shores = 100 m

Time = Distance / Speed

Time taken by the boat to get across is 133.33 seconds

Point C is 150 m from B

Speed = Distance / Time

Velocity of the water is 1.125 m/s

From Pythagoras theorem

So, the man's velocity relative to the shore is 1.35208 m/s

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
