(ii) The distance covered by the antelope after 17 s
v = v₀ + a • t
25 = 0 + 2a
a = 12.5 m/s²
S = ½ • a • t² + v • t
S = ½(12.5)(2)² + 25(14.5)
S = 387.5 m
(iii) How far the cheetah and the antelope after 17 s
v = v₀ + a • t
29 = 0 + 2a
a = 14.5 m/s²
Sc = ½ • a • t² + v • t
Sc = ½(14.5)(2)² + (29)(15)
Sc = 464 m
Total distance between antelope and cheetah after 17s
∆S = S - Sc + 100
∆S = 387.5 - 464 + 100
∆S = 23.5 m
