A stream is flowing at 0.75ms\(^{-1}\) and a boat heading perpendicular for the stream landed at the opposite bank at an angle of 30°. Calculate the velocity of the boat.
1.50ms-1
1.00ms-1
0.86ms-1
0.65ms-1
Correct answer is C
Let the velocity of the boat = Vm/s
0.75/V = adj/hyp = Cos 30°
0.75/V = 0.8660
∴ V = 0.75/0.8660
V = 0.866 ms\(^{-1}\)
