Question

Find thebl acceleration of cheetah if it acquries the velocity of 135km/h with in 2s after he start

Answer 1

Answer:

The acceleration of cheetah if it acquires the velocity of 135km/h within 2s after the cheetah started is calculated as  $a=18.75m/s^{2}$

Explanation:

• We have the equation of motion $V=u+at$

       where,

       V- the final velocity of the body

       u- the initial velocity of the body

       a- acceleration of the body

       t- time taken

• The acceleration is the change in velocity divided by the time taken

       $a=\frac{V-u}{t}$

from the question,

the final velocity of the cheetah $V=135km/h=37.5m/s$

it started from rest so the initial velocity $u=0$

the time to acquire the velocity $t=2s$

now the acceleration of the cheetah $a=37.5/2=18.75m/s^{2}$
