An object starting from rest accelerates at a rate of 3.0 meters per second2 for 6.0 seconds. What is the velocity of the object at the end of this 6.0-second period?

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.
