Question

a boat is travelling at a velocity of 45m/s S. if the current of the river is moving at a velocity of 15m/s due east, what is the resultant velocity of the boat

Answer 1

vy = 10 m/s v2

y + v

2

x = v

2

ground

vx = 1.5 m/s (10)2 + (1.5)2 = v

2

ground

vground = 10.11 m/s

tan θ =

10

1.5

θ = 81.47

Answer 2

Answer:

Explanation:

31 m/s

23° north of east
