Answer:

La magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.

Explanation:

Podemos encontrar la velocidad con la que el martillo golpea el suelo usando la siguiente ecuación:

v_{f} = v_{0} - gt   (1)

En donde:

v_{f}: es la velocidad final =?

v_{0}: es la velocidad inicial = 0 (lo deja caer)

g: es la gravedad = 9.81 m/s²

t: es el tiempo = 9.5 s

Al reemplazar los valores anteriores en la ecuación (1), tenemos:

v_{f} = 0 - 9.81 m/s^{2}*9.5 s = -93.2 m/s                

El signo negativo se debe a que el vector velocidad está dirigido hacia abajo en el eje vertical (y).

Por lo tanto, la magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.

Espero que te sea de utilidad!
