activity Place a penny at the corner of a table as shown in the overhead view in Figure TP4.2. Place a ruler next to the penny and another penny on the top of the part of the ruler that hangs off the edge of the table. Hold the end of the ruler on the table with one hand and use your other hand to flick the end of the ruler with the penny parallel to the table surface. This will project the penny sitting on the corner of the table in a horizontal direction. At the same time, the ruler will slide out from under the second penny, which will fall straight down. Using your smartphone audio recorder, make an audio recording of the two falling pennies. From the recording, determine the time interval between the landing of the two pennies on the floor. What should the time interval be theoretically? Flick the end of the ruler this 10 way
