Cien gramos de hielo a 0 ºC se mezclan con 600 g de agua a 25 ºC. ¿Cuál será la temperatura de equilibrio para a mezcla? Hay que usar cambio de fase. Usar tabla de calores latentes y específicos.

260 miles per hour

explanation:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
