Homework Statement
Okay here's the problem, The coordinate of an object is given as a function of time by x = 4t^2 - 3t^3, where v is in m/s and t is in seconds. Its average acceleration over the interval form t = 0 to t = 2
I wast told the answer is -10m/s^2 but i can't figure out how to get the same anwer.
Homework Equations
Aavg = V2-V1/time
The Attempt at a Solution
ok I've already tryed to plug in 4*2^2 - 3*2^3 and 4*0^2 - 3*0^3 but it doesn't work...
i know if i can get the right values for the change of velocity over 2seconds (my time) i can get the right answer but i can't figure out how to obtain
the change of velocity with the given function
