A race car is timed as it completes laps on an oval racetrack of length L = 3.54m {a} On its rst lap it is found to take take T = 8.39 minutes to go around the track. Calculate the car's average speed over the time taken to complete the lap. \"m = mfs {b} After 3 laps it has been found to taloe 25.1 minutes to complete 3 laps. Calculate the car's average velocity over those 3 laps. pm 2 rule: Part 3) A watermelon is thrown horizontally with a speed of u = 1.03 rule. from the viewing platform of a building H = 14.4 [I]. above ground level.
