You throw a 0.150-kg baseball straight up in the air, giving it an initial upward velocity of magnitude 20.0 m/s. how high does the ball rise? (ignore the effect of air resistance.)

3.00 m

133 m

14.7 m

20.4 m

Option D

20.4 m

Explanation:

Applying the law of conservation of energy

initial kinetic energy = final potential energy

where m is the mass, v is the velocity, g is acceleration due to gravity and h is the height.

Making height the subject then

Substituting the given value of v as 20 m/s and using acceleration of 9.81 then

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.
