(a)  Use the following data to find the velocity and acceleration at t = 10 seconds:

Time (s):0246810121416
Position (m):00.71.83.45.16.37.38.08.4

Use second-order correct (i) centered finite-difference, and (ii) backward finite-difference methods. 


(b)  Use the Taylor expansions for f(x +h), f(x+2h), f(x +3h) and derive the following forward finite-difference formulas for the second derivative. Write down the error term

$$ f^{\prime \prime}(x) \approx \frac{-f(x+3 h)+4 f(x+2 h)-5 f(x+h)+2 f(x)}{h^{2}} $$
