Question

A cheetah accelerates from 15 m/s to 30 m/s in 3.0s what is the cheetahs acceleration

Answer 1

acceleration=increasement of velocity/time
acc=30-15/3
acceleration=15/3
acceleration=5m

Answer 2

acceleration is defined as rate of change in velocity

so here we can write it as

`a = (dv)/(dt)`

`v_i = 15m/s`

`v_f = 30 m/s`

`\Delta t = 3 s`

now using the above equation

`a = (30 - 15)/(3)`

`a = 5 m/s^2`

so acceleration of cheetah will be 5 m/s^2
