1. A dog and a cat ran a race of distance 30 km. In the trail for the race, the dog had an average speed of 2.5 ms-' and maintained that speed for the race. The cat takes 10 s to reach a speed of 15 ms1 and keeps that speed for 20 s, then takes 10 s to come to a rest. It then rests for 5 s to catch his breath before running again. b. Sketch a velocity-time graph for the cat's 1st period c. Determine the cat's average speed over the distance, assuming it continues the races by running and stopping d. Determine where the dog would be when the cat wins
