deceleration = (final velocity - initial velocity) / timed = (vf - vi)/td = decelerationvf = final velocityvi = initial velocityt = timeDeceleration Formula Questions:1) You are driving at 100 m/s and a cat runs out in front of your car. You stop rapidly, which takes 5 seconds, and miss the cat. What is your deceleration?Answer: The initial velocity, vi = 100 m/s. The final velocity, vf = 0 m/s. The time, t = 5 sec.d = (vf - vi) /td = (0 m/s - 100 m/s)/ 5 secd = -100m/s / 5 secd = - 20 m/s2

i hope this can help you. :)
