Assignment 39. A driver is travelling at 18.0 m/s when she stops a sign the reads "Bridge Out Ahead". It takes her 2.0 s to react and begin braking. The car accelerates at - 1.5 m/s2. a. Draw a v-t graph of this motion. b. How much time was required to stop the car once the brakes were applied? c. How far did the car travel after the driver saw the sign. d. What is the average speed for this trip? 40. A trip consists of three parts. During the first part the object accelerates from rest to 25 m/s in 10.0 s. In the second part the object travels at 25 m/s for 15.0 s. Then, it slows down to rest in 75 m. a. Calculate the total distance traveled. b. Calculate the total time take. c. What was the average speed for the entire journey? Page 23 of 24
