6) An alien on a foreign planet similar to earth drops a 5 kg book from a height of 4 m (these are giant aliens). The book falls because of a force of 11.2 N acts on it.
a. What is the value of “g” on their planet?
b. Bonus question: The average height of a human is 1.6 m. How could these
aliens have grown so much taller than us?

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

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.
