A float thrown on the surface of the water in the river swam downstream the distance S = 10 m during the time interval delta t = 4.0 s. determine the module of the speed of the passage of time.
These tasks: S (distance that the float swam downstream) = 10 m; Δt (time interval) = 4 s.
The flow velocity module is calculated by the formula: V = | S / Δt |.
Calculation: V = | 10/4 | = 2.5 m / s.
Answer: The module of the current velocity is 2.5 m / s.
