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?

2. A car moves from `A` to`B` in `10.0\ s`. It turns around at `B`, and then moves from `B` to `C` in `10.0\ s`. (Assume this car moves under a constant speed in each time intervals.) 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`
