Stand next to a wall that travels at 30 km/s relative to the sun. with your feet on the ground, you also travel at the same 30 km/s. do you maintain the speed when your feet leave the ground?

Yes

Explanation:

We will able to maintain that because of inertia.

Inertia is the property of an object to maintain the state of rest or motion unless an external force is applied to the object. This is the conclusion of the first law of motion.

some examples of inertia are when a bus suddenly stops and we feel a push.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head
