A car traveling 16.0m/s crashes into concrete embankment and stops in 0.08s. Calculate:

the initial speed in mi/hr
the average acceleration of the car during the collision in m/s^2
Please show all work than you

35.79 miles per hour { Google 16 m/s = miles/hour }

a = change in velocity/change in time

= -16/.08 = -200 m/s^2
