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.
A
1.50ms-1
B
1.00ms-1
C
0.86ms-1
D
0.65ms-1
correct option: c
Let the velocity of the boat = Vm/s
0.75/V = adj/hyp = Cost30°
0.75/V = 0.8660
∴ V = 0.75/0.8660
V = 0.86-1
0.75/V = adj/hyp = Cost30°
0.75/V = 0.8660
∴ V = 0.75/0.8660
V = 0.86-1
