The driver of a car traveling at 110 km/h slams on the brakes so that the car undergoes a constant acceleration, skidding to a complete stop at 4.5 s. What is the average acceleration of the car during braking?
Added by Steven S.
Step 1
The problem states that the car is traveling at 110 km/h, so we need to convert this to m/s. 1 km/h = 1000 m/3600 s = 10/36 m/s Therefore, the initial velocity of the car is: 110 km/h * (10/36 m/s) = 1100/36 m/s = 30.56 m/s Show more…
