Question

A cheetah can start from rest and attain the velocity 72km/h in 2 seconds. Calculate the acceleration of cheetah.

Answer 1

Acceleration(a)=21.60 km/h or 21,600 m/s

Step-by-step explanation:

Since you have the initial velocity(0, because it starts from rest) and the final velocity 72 km/h or 72,000 m/s. so...

`a=(Vf-Vi)/(t)\\ a=(72,000 m/s-0)/(2s)\\ a=(72,000 m/s)/(2s)\\ a=36,000m/s or 36 km/h`
