A race car moves such that its position fits the relationship(adsbygoogle = window.adsbygoogle || []).push({});

x(t) = (4.4 m/s) t + (0.91 m/s^3) t^3 (yes cubed)

where x is measured in meters and t in seconds.Approximate the instantaneous velocity at t = 2.6 s, using a time interval of 0.2 s. Answer

in units of m/s.

i am just stuck and dont even know where to start
