we have,

$"acceleration" = 6 " m/s"^2$

$"initial velocity" = 10.5" m/s"$

$"final velocity" = 12.2" m/s"$

$color(white)(OOO$

$"acceleration" = ("final velocity " - " initial velocity")/ "time taken"$

$"time taken to speed up from 10.5m/s to 12.2m/s" = (12.2-10.5)/6 = 1.7/6 = 0.28 " seconds"$

A cheetah can accelerate at up to 6.06.0 mm/s^2/s^2. How long does it take for a cheetah to speed up from 10.510.5 mm/s/s to 12.212.2 mm/s/s?
