A position vs time graph is shown below for a cyclist. Motion to the right is positive. 10 9 8 x (meters) 7 543 2 1 0 12345678910 time (sec) a) What is the cyclist's position at t = 0? 6 m b) What is the cyclist's velocity at t = 8 s? X m/s c) How would you describe the cyclist's motion at t = 4 s? A person starts at position x = 1 m, and then walks to x = 4 m. The person then walks to x = -2 m. a) What is the person's total distance traveled from start to finish? 9 m b) What is the person's displacement (change in position) from start to finish? -3 m c).If.the.entire journey takes 12 seconds from start to finish, what is the person's average velocity during the journey? m/s
