Question

Below is a picture of a swimmer in a river. Looking at the vectors being added is the swimmer going downstream or upstream?

Downstream, the current is helping the swimmer go faster relative to the land.

Upstream, the current is slowing the swimmer down.

Answer 1

I got A or Downstream, the current is helping the swimmer go faster relative to the land.

I am about to submit my quiz to see if it is correct.

Answer 2

Answer: Downstream, the current is helping the swimmer go faster relative to the land.

The current is helping the swimmer go faster relative to the land.

velocity of stream =
`v_w`

velocity of swimmer =
`v_s`

During upstream, swimmer would move against the stream. Hence, his velocity =
`-v_s`

Net velocity,
`v_f=v_w-v_s`

During downstream, swimmer would move along the stream. Hence, his velocity =
`v_s`

Net velocity,
`v_f=v_w+v_s`
