Table 2 shows the velocity (v [m/s]) of a cyclist recorded at different times (t [s]) after they started pedalling from a standstill. It has been suggested that the function v(t) = at + a2t may accurately describe the relationship between v and t. Use this information to complete the following tasks: i 0 Table 2 1 2 3 4 ti 0.0 0.5 2.0 7.0 14.0 V 0.0 2.5 4.8 6.5 7.0 a) Use Multiple Linear Regression to compute values of a and a which give the best fit of v(t) to the recorded data. Plot the fitted curve and datapoints together on an excel chart. b) Calculate the coefficient of determination for the fitted curve obtained in (a)
