Question

Aman can row a boat at 13 m/s in still water. If he
aims at crossing to the opposite bank of a river
flowing at 5 m's, at what angle to the bank of the
river must herow the boat
A. 67.40 B.210 C. $6.80 D. 22.60​

Answer 1

ans..

When a person rows a boat across a river, the direction of the boat depends on the velocity due to the effort of the person and the velocity of the river currents. If the person rowed the boat at an angle to the horizontal, the person can offset the velocity of the river currents and thus proceed directly across the river.
