Calculate the kinetic energy of an 88-kg scooter moving at 10 m/s . express your answer to two significant figures and include the appropriate units.

Given:

m(mass)=88kg

v(velocity)=10m/s

Now kinetic energy=1/2(mv^2)

Where m is the mass

v is the velocity

Substituting these values we get

Kinetic energy=1/2(88 X 10 x 10)

Kinetic energy = 4400 N

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.
