Question

Как найти Vсоб.если известно только V теч. и Vпр.теч.

Answer 1

V против течения +  v течения

Answer 2

Finding Velocity Using Initial and Final Time

To find the velocity (V) when only the initial time (t0) and the final time (t) are known, you can use the formula:

V = (Vf + Vi) / 2

Where: - V is the velocity - Vf is the final velocity - Vi is the initial velocity

This formula is derived from the equation for average velocity, which is the total displacement divided by the total time.

Example Calculation

Let's say the initial time (t0) is 3 seconds and the final time (t) is 8 seconds. Using the formula, we can calculate the velocity:

V = (Vf + Vi) / 2

Now, let's substitute the values: V = (8 + 3) / 2 V = 11 / 2 V = 5.5 m/s

So, when the initial time is 3 seconds and the final time is 8 seconds, the velocity is 5.5 m/s.
