Answer:
7.407 m/s^(2)

Step-by-step explanation:

In this question we are asked to find the cheeta's accelaration and we assume it is constant. Therefore, we can use the folowing equation:


V=V_(o)+at (1)

Where:


V=80 (km)/(h) (1000 m)/(1 km) (1 h)/(3600 s)=22.22 m/s is the cheeta's final speed


V_(o)= 0 m/s is the cheeta's initial speed


t=3 s is the time in which the cheeta passes from
V_(o) to
V


a is the cheeta's acceleration

Isolating
a from (1):


a=(V)/(t) (2)


a=(22.22 m/s)/(3 s) (3)

Finally:


a+7.407 m/s^(2)
