Derivative Practice: For each equation, find the equation for the instantaneous velocity and the instantaneous acceleration and evaluate at the specified time (if given).

1. x = t3 + 2t2 + 10 t = 2 s

2. x = 4t4 + 1/2 t3 + t t = 3 s

3. x = 1/2t2 + 5t + 6 t = 4 s

4. x = sint +2t

5. x = cos(2t)

6. x = 2/3t2 + t4
