I can't figure out how you would solve these problems? Can someone explain what I would have to do, step by step, to get the answers?
I don't know how I would make a velocity vs. time graph out of these, meaning I just don't know how to get the numbers for the graph?
1) A car accelerates form 31.0 m/s to rest over a displacement of 130.0 m. What is the car's acceleration, and how long did it take to
stop?
2) A jet needs to reach a takeoff speed of 75.0 m/s. If the runway is 1625 meters long, what minimum acceleration is needed? How much time will it take to reach the takeoff speed?
