Answer the question.

An artillery unit is testing a newly develop training rocket for the Arms Force (see Table Q3). Table Q3 t (seconds/s) 0 0.2 0.6 1.2 1.8 2.4 h (distance/meters) 0 28 99 915 1048 2099 The following data was collected for the distance travelled versus time for the training rocket during upward trajectory. (a) Estimate the maximum velocity achieved by the rocket. b) If there was a recording error at t=0.2 s and omitted from the datasheet, provide the best possible estimation for rocket velocity at t= 1.8 s? Show at least two difference approaches as evident. Figure Q3. Training rocket flight trajectory
