10. Acceleration is sometimes expressed in multiples of g, where g=9.8m/s^2 is the acceleration due to Earth's gravity. In a car crash, the car's velocity changes from 32m/s to 0m/s in 0.15s In terms of g, what is the average acceleration of the car during the crash?

a=final v-initial/time

a=0-32/0.15
