A car traveling west in a straight line on a highway decreases its speed from 30.0 meters per second to 23.0 meters per second in 2.00 seconds.The Cars average acceleration during the time interval. is

Acceleration, a =  (v - u) / tInitial Velocity, u = 30 m/sFinal Velocity, v  =  23 m/stime                 t  =  2.00 secondsa = (23 - 30) / 2 a = -7 / 2 = -3.5 m/s2So the acceleration  is negative, which means it is a deceleration of 3.5 m/s2.

Answer:3.5 m/sExplanation:
