Answer:
d = 0m
v_avg = 2.5 m/s
Explanation:
A) The distance traveled by the swimmer was:
However, the displacement is zero because the final position of the swimmer is the same as the initial position.
displacement = 0m
The average velocity was:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
A) La distancia recorrida por el nadador fue:
Sin embargo, el desplazamiento es cero porque la posición final del nadador es la misma que la posición inicial.
desplazamiento = 0m
La velocidad promedio fue:
