The cheetah, which is the fastest land mammal, can accelerate from 0.0 mi/hr to 70.0 mi/hr in 3.0 seconds.
What is the acceleration of the cheetah? Give your answer in units of mph/sec.

Sagot :

Initial velocity of Cheetah(V1) = 0.0 mi/hr
Final velocity of Cheetah(V2) = 70 mi/hr
Time for acceleration(T) = 3 seconds.
We know the formula
Accelaration(A) = Velocity/Time
So
A = (V2 -V1)/T
   = (70 -0)/3
   = 70/3
   = 23.33mph/sec
So the accelaration of the Cheetah is 23.33 mph/sec.
