a cheetah can go from a state of resting at running at 20m/s in just two seconds.what is the cheetahs average acceleration

A.40 m/s
B.40 m/s^2
C.10 m/s
D.10 m/s^2

Respuesta :

acceleration = change in velocity/change in time
so...
a = 20 m/s / 2 seconds
a = 10

hope that helps :)
a.
40 m/s
You have to multiply 20 times 2 because there were 2 seconds.
