Question

The velocity vector of the boat has two components: v1 is the velocity of the water and v2 is the velocity of the boat relative to the water. If v1= 3 km/h and v2= 5 km/h, determine the velocity vector of the boat.

Answer 1

what is the answer??

Answer 2

7.55 km/h @ 25.2 degrees

Answer 3

ok so here are the steps
first resolve the forces into components
horizontal component of v2=5cos(40)=3.8
horizontal component of v1=v1 (as v1 is horizontal (angle=0))
total horizontal resultant=3.8+v1=6.8
vertical component of v2=5sin(40)=3.2
vertical component of v1=0 (angle=90)
total vertical resultant=3.2
magnitude of velocity vector=sqrt(3.2^2+6.8^2)
direction of velocity vector=tan inverse (3.2/6.8)

Answer 4

thank you so much!! :D
