有人可以幫我嗎🥺🥺

18. (III) An automobile traveling 95 km/h overtakes a 1.10-km-
long train traveling in the same direction on a track parallel
to the road. If the train's speed is 75 km/h, how long does it
take the car to pass it, and how far will the car have traveled
in this time? See Fig. 2-39. What are the results if the car
and train are traveling in opposite directions?
v = 95 km/h
1.10 km
v = 75 km/h

25. (11) A car moving in a straight line starts at x = 0 at = 0.
It passes the point x=25.0m with a speed of 11.0 m/s at
13.00s. It passes the point x = 385 m with a speed of
45.0 m/s at 20.0s. Find (a) the average velocity and
(b) the average acceleration between 13.00s and
