Hello, I am currently by some reason struggling with this problem. I cannot seem to get the correct reasoning here. I would appreciate any help! 1. The problem statement, all variables and given/known data Ann and Lisa cross the 100 m finish line at the same time, 10.2 s after start. Both had constant acceleration until they reached max speed. Ann used 2.0 s to reach max speed. Lisa used 3.0 s to reach max speed. The max speed was sustained until they reached the finish line. 1) What was their respective acceleration? 2) What was their respective max speed? 3) Who was in the lead after 6.0 s and by how many meters? 2. Relevant equations [itex]v=v_0+at[/itex] [itex]x=x_0+v_0t+.5at^2[/itex] [itex]v^2=v^2_0+2aΔx[/itex] 3. The attempt at a solution 0 = start, 1 = max speed reached, 2 = goal. For Ann: [itex]t_1=2s [/itex], [itex]t_2=8.2s [/itex], [itex]v_0=0 [/itex], [itex]x_0=0 [/itex], [itex]v_1=v_2 [/itex] [itex]v_1=at_1[/itex], [itex]x_1=.5at^2_1[/itex], [itex]v_1t_2=x_2[/itex] Here I am struggling, If I do this for both I get 8 unknowns with 6 equations.
