a cheetah goes from standing still to running at 60 mph in 3 seconds. what is the cheetahs acceleration in standard international units?

Hang on...

Initial velocity (u) : 0mph = 0m/s (rest)
Final velocity (v) : 60mph = 26.822 m/s
Time taken (t) : 3 seconds

Now,

Acceleration= (v-u)/t

= 26.822 - 0 / 3
= 8.94

Therefore the acceleration is 8.94 m/s^2
