. Question 3 Not yet graded / 2 pts This question relates to the recorded vertical velocity of a lunar module as it descends to meet the surface. The velocity data are shown in the table below. The time = O is the point at which the final descent program started. Remember to include units in all answers. Using the first central difference formula, computer the derivative (the acceleration) of the module at 4 s.
