1. A car moves from `A` to `B` in `5.0` second as shown in the figure.
(a) What is the initial position, `x_i`, of this car?
(b) What is the final position, `x_f`, of this car?
(c) How many distance, `d`, this car moved?
(d) What is the displacement, `∆x`, of this car?
(e) What is the average speed of this car?
(f) What is the average velocity of this car?

a) Draw a position-time graph about this motion.
b) Find the velocity of this car from `A` to `B`
c) Find the velocity of this car from `B` to `C`
d) Find the average velocity of this car from `A` to `C`
