A toy truck with a mass of 0.67 kg is moving to the right with a velocity of 5.1 m/s when it strikes a toy car that has a mass of 0.15 kg and is also moving to the right. If, after the collision, the velocity of the truck is 4.2 m/s to the right and the velocity of the car is 4.6 m/s to the right, what was the initial velocity of the car?

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.
