Thread: Velocity of a car

The Velocity of a car is given by v(t)=120(1-0.85^t)

How can i calculate the average and instant acceleration of the car in the first 5 seconds/

average acceleration from to ...



understand that the instantaneous acceleration calculation requires calculus.



What do you know about derivatives of exponential functions?

my teacher never taught us derivities instead we use something like (f(X)+(X.0001))/.0001

ok, then ... you're making an estimate of the instantaneous rate of change of velocity. get out your calculator and do it.
