8. Scenario: A time t = 0, clay ball I it droppedfrom rest at 1. V = 0 8 v : 0 the top ofa building. At the some time, identical clay ball 2 is launched upward'om ground level. At time t= T, the 'V = V0 two collide and Stick. Just aer the collision. the combined obfect has upward speed v0. At time t = 2T, the combined obfect is momentarily at rest at the top of the building. (Source: AP Physics 1 Workbook, College Board, 2019) PART A: The graph on the left below shows velocity as a function of time, where up is positive. The velocity of the combined object is already drawn for T
