Answer:
<u>velocity of swimmer relative to ground = 3 i -5 j</u>
Explanation:
- To cross a river the swimmer swims relative to river in perpendicular direction.
Velocity of river = -5 j (south)
Velocity of swimmer relative to river = 3 i(north)
So
<h2>Velocity of swimmer relative to ground = Velocity of swimmer relative to river + Velocity of river</h2>Velocity of swimmer relative to ground = 3 i -5 j
So magnitude of total velocity is =
=
