The Lamborghini Diablo sports car can accelerate from 0 kilometers/hour to 99.2 kilometers/hour in 4.0 seconds. What is the acceleration of this car in kilometers/hour^2. (hint: you must convert 4.0 seconds before putting it into the equation.)

99km/hr / 4sec * 3600sec/hr = 89100 km/hr^2

acceleration = (Change in velocity) / (time in hours)

4sec / (3600sec/hr) = 0.0011111 hour

accel = (99.2km/hr) / (0.0011111 hr)=89286km/hr^2
