Let V⃗ 1 = -6.3 i^ + 8.5 j^ and V⃗ 2 = -4.5 j^ + 4.1 i^. Determine the magnitude of V⃗ 1.
Determine the direction of V⃗ 1
Determine the magnitude of V⃗ 2
Determine the direction of V⃗ 2.

Scissors and a seesaw both cut things that’s the only comparison

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

The answer is b, i got it right on a test. hope it ; )
