A 2023 Chevrolet Corvette Z07 coupe can accelerate from rest to 60 mi/h in about 2.8 s according to MotorTrend. Suppose the Corvette moves through a distance of 0.25 miles during this period of constant acceleration. Suppose the driver of the Z07 then turns off the engine and lets the car coast to rest with a different constant acceleration. The total time for this motion (from rest to rest) is 7.9s, and the total distance covered is 0.32 miles. (a) What is the magnitude of the Corvette ZO7's acceleration during the time it is speeding up from O to 60 mi/h? (b) What is the magnitude of the Corvette Z07's acceleration during the time it is slowing down from 60 mi/h to 0? Please express your accelerations in m/s2
