Why don't asteroids have atmosphere

In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80m/s2. Ignore air resistance. A flea jumps straight up to a maximum height of 0.460m.

states that the velocity of the fluid in contact with the surface is equal to the velocity of that surface

When you jump up, you exert an action force on the ground. What's the reaction force? A. your weight B. Earth's gravity C. the ground pushing on you D. your body moving upward

Which of these is true about acceleration?
