The changing of position of an object with respect to time t is given by the following function (over the time period 0 < t < 10s): x (t) = 5t+2t + 3t+2 Providing evidence of your approach in a spreadsheet or word document, using the provided code for forward, backward and central difference method, determine the velocity of the object at t = 4s considering step sizes h = 1, 0.1 and 0.01. Compare the accuracy and cost of the approach. How do the results compare to the analytical solutions? Furthermore, providing evidence of your approach in a spreadsheet or word document, using the provided code for forward, backward and central difference methods, determine the acceleration of the object at t 6s considering step sizes h = 1, 0.1 and 0.01. Compare the accuracy and cost of the approach. How do the results compare to the analytical solutions? -
