A cat is being chased by a dog. Both are running in a straight line at constant speeds. The cat has a head start of 3.8 m. The dog is running with a speed of 8.9 m/s and catches the cat after 6.0 s. How fast did the cat run?
In 6 secs, the dog covers- S=vt 8.9*6 = 53.4 m. In the same time, the cat covers, 53.4-3.8 = 49.6 m. Thus, speed of the cat, v= s/t, = 49.6/6 = 8.267 m/s
