Find the acceleration when velocity is 0. Velocity equation is v=t^2-6t+9

Answer 1

The acceleration is the derivative of the velocity as a function of time.

a = dv/dt

Using the equation v = t² - 6t + 9, we have:

a = 2t - 6

If v = 0 you can find the value for t; 0 = t² - 6t + 9. Isolating t, you find that t = 3.

If you substitute t = 3 in acceleration equation you will find that a = 0.
