VelociTy and acceleroTion HinT for The following: JusT like velociTy Tells us how posiTion changes wiTh Time (slope of an xT graph)! acceleraTion Tells us how velocitg changes wiTh Time. The graphs below show The velociTies (v) of Two differenT people running, as a funcTion of Time (T). You will need no calculaTions for The quesTions below, only The graphs. BLIT, be sure to show your work! V (m/s) A v (m/s) 12345678910 12345678910 ParT 1: (answer for boTh graphs) During which inTervals of Time is The acceleraTion posiTive? NegaTive? ParT 2: (answer for boTh graphs) Is The acceleraTion ever 0? If so, when?-l ParT 3: Which person runs farTher during The. first 10 seconds? (HinT: whoT are The uniTs of 'P-f)
