Example #1 Jimmy is at rest in his corvette. Suddenly he hits the gas and accelerates at a constant rate of 4 m/s2. What will his velocity be after 5 seconds? forward

Example #2a A plane is moving at a speed of 50 mph when it lands on a runway. Accelerating uniformly, it comes to a stop after covering a quarter mile. How long did it take to stop? What was its acceleration?

Example #2b A plane is moving at a speed of 50 mph when it lands on a runway. Accelerating uniformly, it comes to a stop after covering a quarter mile. How long did it take to stop? What was its acceleration?

Example #3 A race car travelling at 60 mph accelerates uniformly to a speed of 90 mph, covering 50 meters in the process. What was the car’s acceleration?
