Responder:

El remolque del tractor no atropellará a la vaca.

Explicación:

Dado lo siguiente:

Velocidad del tractor remolque: 69 km / h

Tiempo necesario para detenerse después de aplicar los frenos = 4 segundos

Distancia de vacas desde el remolque del tractor = 25 metros

Por lo tanto, la distancia recorrida por el remolque del tractor después de aplicar los frenos:

Velocidad del tractor remolque / Tiempo

69 km / h = (69 * 1000) m / 3600s = 69000m / 3600s = 19.17m / s

(19,17 m / s ÷ 4 s) = 4,8 m

Como la distancia de la vaca está más lejos (25 m), el remolque del tractor no pasará por encima de las vacas
