Question

The position of a particle in meters is given by x =2.5t + 3.1t ^2 - 4.5t^3, where t is the time in seconds. What are the instantaneous velocity and instantaneous acceleration at t = 0.0 s? At t = 2.0 s? What are the average velocity and average acceleration for the time interval 0 greater than or equal to t less than or equal to 2.0 s?
