Jasmine Silva · Answer 1

Acceleration of cheetah is 10 m/s²

Explanation:

We have equation of motion v = u + at

Initial velocity, u = 0 m/s

Final velocity, v = 50 miles/hr = 80 km/hr = 22.22 m/s

Time, t = 2.22 s

Substituting

v = u + at

22.22 = 0 + a x 2.22

a = 10 m/s²

Acceleration is 10 m/s²

Acceleration of cheetah is 10 m/s²
