The cheetah and the deer are moving at velocity of 20 ms-1 and 15 ms-1 respectively.
Diagram 2 shows the cheetah has successfully caught the deer and the two of them are moving at the same velocity, v ms-1 .
Rajah 1 menunjukkan seekor harimau kumbang yang berjisim 50 kg sedang mengejar sesekor rusa yang berjisim 60 kg. Harimau kumbang dan rusa masing-masing bergerak pada halaju 20 ms-1 dan15 ms-1 .Rajah 2 menunjukkan harimau kumbang berjaya menangkap rusa dan kedua-duanya bergerak dengan halaju yang sama, v ms-1 .
