Cheetahs the worlds fastest land animals can run up to about 125km/h. a cheetah chasing an impala runs 32m [N], then suddenly turns and runs 46m [W] before lunging at the impala. the entire motion takes only 2.7seconds.

a) determine the ceetahs average speed for this motion.

b) determine the cheetahs average velocity

Kayden Ibarra · Answer 1

Av Speed = total distance / time time = 32 + 46 / 2.7 = 28 m/sec

Av velocity = total displacement / time total = S / t

S = sqrt (32^2 + 46^2) = 56 m

Av Velocity = 56 / 2,7 = 20.75 m/sec

with angle tan^-1 = 0.7 north west (about 35 degrees north west)
