Question

A canoe has a velocity of 0.47m/s southeast relative to the earth. The canoe is on a river that is flowing 0.52m/s east relative to the earth.

Find the magnitude of the velocity of the canoe relative to the river.

Answer 1

I thin u r familiar with the this
If there r 2 objects A,B with different velocities

The V of A relative to B = V of A relative to earth + V of earth relative to B (usually -B)

u this and u could solve the problem easily
