I'm confused on how to tell what equation to use to solve this. Can you explain how to determine that are well. Thank you! While waiting for the CABS bus on the way home from physics class, yourfriend looks up at the traffic signal and says, "I wonder how big the trafficsignal is, it can't be more than half a meter tall?" Having only a rock, thetimer on your phone (no service), your knowledge of kinematics, and allthe time in the world, you two decide to figure out its vertical size L.First you throw the rock vertically upwards so that the maximum heightof the rock just matches the height of the bottom of the traffic signal atthe peak of the rock's trajectory. Your friend times that the rock is in theair for a total of tpottom = 2.1 seconds from when you release it to when youcatch it (averaging over several trials). Next you throw the rock verticallyupwards so that it matches the height at the top of the traffic signal at thepeak of its trajectory, and measure it to take tropover several trials). What is the approximate vertical size L of the trafficsignal?2.3 seconds (averaging
