70) Earth continually moves about 30 km/s through space, which means the wall you stand next
to also is moving at 30 km/s. When you jump vertically the wall doesn't slam into you because
A) the speeds of you and Earth cancel out.
B) you're moving horizontally just as fast as the wall.
C) your upward motion is small compared with Earth's speed.
