Answer
For (a) and (c), see the figure below.
(b) A car slows down, from 40 mi/h, while moving toward the east north to take a sharp turn toward the south and then speeds up again.
The speeding up rate and the slowing down rate are having the same magnitude of 2 $\rm m/s^2$. The first stage of motion (the slowing down) took about 2 minutes as same as the speeding up stage to reach 40 mi/h again.
Find the whole distance traveled by the car during this trip.
