P1200 Group Work #3 (Friday) Date: 9/15/2023 Problem 2 While waiting for the CABS bus on the way home from physics class, your friend looks up at the traffic signal and says, "I wonder how big the traffic signal is, it can't be more than half a meter tall?" Having only a rock, the timer on your phone (no service), your knowledge of kinematics, and all the time in the world, the two of you decide to figure out its vertical size L. (a) First you throw the rock vertically upwards so that the maximum height of the rock just matches the height of the bottom of the traffic signal at the peak of the rock's trajectory. Next you throw the rock vertically upwards so that it matches the height of the top of the traffic signal at the peak of its trajectory. All initial and final elevations are at the same y-coordinate for every toss and catch. Draw a sketch of the two trajectories. (b) Your friend times that the rock is in the air for tbottom = 1.05 seconds from when you release it to when it just reaches the bottom of the traffic signal (averaging over several trials). He also measures it to take ttop = 1.15 seconds from when you release it to when it just reaches the top of the traffic signal (averaging over several trials). What is the approximate vertical size L of the traffic signal? 3Problem 1 During a baseball game, the batter swings and hits a foul ball. At time to, the ball leaves the bat with velocity vi = 41 m/s directed 62 above the horizontal. At time ty, the ball reaches the peak of its trajectory, at which point its velocity is of. (a) Which option below correctly uses the tip-to-tail rule of vector addition to relate to- gether the vectors vi, uf, and Av? Note: these vector diagrams are drawn in the plane of the ball's direction of travel. of Uf Au Au (b) What is the direction of the ball's acceleration vector while it's in the air? Explain why your answer is consistent with the vector diagram you chose in part (a) above.P1200 Group Work #3 (Friday) Date: 9/15/2023 (c) How much time passes between the ball being hit and reaching the peak? a a ((1) Find the horizontal compmient (Am) and the vertical emnpenent (A3,!) of the hall's displacement [3) between being hit and reaching the peak
