1. The problem statement, all variables and given/known data A car's velocity as a function of time is given by Vx (t) = alpha + beta (t)^2, where alpha = 3.00m/s and beta = .100m/s^3. Calculate the instantaneous acceleration for t= 5seconds 2. Relevant equations ax = dv/dt 3. The attempt at a solution My first attempt is to get various times and get their corresponding acceleration. vx @ 0s = 3m/s vx @ 1s = 3.1m/s vx @ .5s = 3.025 m/s vx@ 5s = 5.5 I know compared a= 3.1-3/1-0 = .1 3.035-3/.5-0 = .05 the average would end up being around .1 I know this problems involved more calculus math, derivitives etc. How do I apply this here.
