An airplane flies horizontally at a speed of 489 km/h and drops a crate that falls into the horizontal ground below. neglect air resistance. a) if the altitude of the plane was 715m, then how far, horizontally in meters, did the crate move as it fell to the ground?
b) what was the speed of the crate, in m/s, just before it hit the ground?
