Acar traveling at 31 m/s starts to decelerate steadily. it comes to a complete stop in 7 seconds. what is its acceleration

Vf=V1+at
0=31+a(7)
-31/7=a
a=-4.43m/s^2

Hope this helps.

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
