In the fastest measured tennis serve, the ball left the racquet at 73.14 m/s. a served tennis ball is typically in contact with the racquet for 27.0 ms and starts from rest. the direction of the velocity of the ball just after it left the racquet is the positive x direction. assume constant acceleration. a. what was the x component of the ball's acceleration during this serve?
b. how far did the ball travel during the serve?

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
