1. Apply your mathematical models to your allocated car. Use the given data for the 0 – 28 m/s and 400m times to calculate the:




1. value of the coefficient A



2. maximum velocity



3. maximum acceleration.




Given: t (0-28 m/s) is 1.9s, t (400m) is 10.50s & tmaxspeed is 7.1s.



Given velocity equation :V (t) = A (1 - e^((-t)/(t maxspeed)))
