A cheetah starting form rest can reach a maximum speed of 28m.s in 2s and it can maintain this maxium speed for 15s after this it must rest.

suppose an antelope and a cheetah initially at rest are seperated by a displcament of magnitude 100m.The antelope and cheetah see each other simultaneously and then start running westwards immediately.

1.1Calculate the acceleration of the cheetah in the first 2s.

1.2 Calculate the maximum distance that the cheetah can run before it comes to rest.

1.3 If the acceleration of the antelope for the first 2s of the chase in 12.5 m.s2 , determine whether the cheetah will catch the antelope
