Figure P2.55 shows the position as a function of time for an apple that falls from a very tall tree. (a) At what time does the apple hit the ground? (b) Use a graphical approach to estimate and plot the acceleration as a function of time. (c) Make a sketch of the velocity of the apple as a function of its height above the ground.
