What is the landing velocity of an object that is thrown vertically down with a velocity of 5 m/s from a height of 25 m?

The relevant equation we can use in this case would be:

v^2 = v0^2 + 2 a d

where:

v is our final velocity or landing velocity = ?

v0 is the initial velocity = 5 m/s

a is acceleration due to gravity = 9.81 m/s^2

d is distance = 25 m

So:

v^2 = 5^2 + 2 (9.81) 25

v^2 = 515.5

v = 22.70 m/s

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.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
