Two cars start from rest side by side and travel along a straight road. Car A accelerates at 4 m/s^2 for 10 s and then maintains a constant speed. Car B accelerates at 5 m/s^2 until reaching a constant speed of 25 m/s and then maintains this speed. Construct the a–t, v–t, and s–t graphs for each car until t = 15 s. What is the distance between the two cars when t = 15 s?

Bob is cruising leisurely on his bike at 2 m/s when Jim passes him, traveling at a constant 10 m/s. Bob immediately begins accelerating at 2.2 m/s² until he reaches his maximum velocity of 13.5 m/s. He continues cruising at that speed until he catches Jim. How long did it take him to catch up to Jim? (Assume the clock started at the instant he began to accelerate.) t = How far did he have to go to catch up to Jim? Ax = %3D

George, the absent-minded professor, drives his car 5.0 miles due east alonga straight road to the grocery store. Upon arriving there 15 minutes (0.25 h) after he left home, he suddenly realizes he forgot his grocery list. He immediately turns around and heads back towards home. After travelling 6.8 miles due west in 12 minutes (0.20 h), the car runs out of gas. What is his average speed during the not-quite-completed trip?
The figure shows an acceleration- time graph of a particle with a starting velocity at 60 m/s and the distance travelled is 200 meters at 10 seconds. Draw the (v-t), and (s-t) graphs of the particle. Determine the total distance travelled and its velocity at 18 seconds. 4m/s? 10s te14s t= 18s Am/s
A car starts from rest. It accelerates at constant acceleration for 5.0 seconds during which the car covers a distance of 125 m. After that the car continues at that speed for 22 seconds, after which the car slows down at a constant deceleration of – 4.5 m/sec2 until coming to a complete stop. Draw a v vs t, graph, label all the relevant data, and use the graphical method to determine total distance traveled.
A driver is driving uphill. He maintained his throttle, causing his car to constantly decelerate as it is coming up the hill. The road going up the hill is 217 m long and it took him 8.8 seconds to get to the top of the hill. His speed has reduced to 22 m/s at that point. What was the car's acceleration (include a negative sign in your answer)? Hint: the initial position of the car can be set at the origin.
