Suppose the velocity v of a motorboat coasting in water satisfies the differential equation dv/dt=kv2. The initial speed of the motorboat is v (0) = 10m/s and v is decreasing at a rate of 1 m/s^2 when v = 5 m/s. Required:
How long does it take for the velocity of the boat to decrease to 1 m/s^2 to 1/10 m/s^2, when does it come to a stop?

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.
