Question

people at instants separated by equal time intervals. Problem 10 The diagrams below show the positions of two Both people jog up to a starting line (dotted line in the figure) and then begin to accelerate in a drill at practice. (a)2 pts] Who is going fastest before they reach the starting line? How can you tell? (b)[8 pts] In the graphs below, show the positions, velocities, and accelerations of Kat and Jordan (use two curves per graph; label the curves K and J). Incorporate all the quantitative information you have into the graph (c)12 pts] Which person has the largest average velocity at the last time interval shown? How can you tell? (d)2 pts] If the time interval between dots is 1s, and the separation between bold lines is 1m, what is Jordan's average velocity from the time he crosses the starting line? (e)2 pts] Who has the largest average velocity over the entire time interval shown in the motion diagram? Explain briefly Kat Jordan a t Acceleration Velocity Position
