Question

A river of width 120m which flows at a speed of 8m/s if a man swims with speed of 5m/s at an angle of 127 with the stream his drift on reaching the bank is

Answer 1

Velocity in x direction is 8-3=5m/s Velocity in y direction is 4m/s Time taken is 120/4=30

second drift is 5*30=150m

Answer 2

Answer:150 m drift

Explanation: as the velocity of man makes an angle of of 127 degree with the stream so the the two components of velocity of man will be 4i and 3j time taken by the man to cross the river is 30 seconds show the drift of the man will be

Drift=5(horizontal component)×30=150m
