Leslie is speeding up to merge with traffic. When she begins to speed up, she has a velocity of 7.0 m/s west. When she merges with traffic 7.0 seconds later, she is traveling 23 m/s. Assuming east to be the positive direction, what is Leslie’s average rate of acceleration during this period? Select one:

a.2.3 m/s ^{2}

b.1.9 m/s ^{2}

c. -1.9 m/s ^{2}

d.-2.3 m/s ^{2}
