Question

A cheetah can accelerate 96km/h in 2s what is its average acceleration

Answer 1

Given: A cheetah can accelerate $96km/h$ in $2 sec$

To find: Average acceleration.

Solution:

The speed at which the cheetah can accelerate is $=96km/hr$

∴ The final velocity is $= 96 km/h=26.66m/s$

The initial velocity will be $= 0 km/hr = 0m/s$

Initial time taken will be $= 0s$

Final time taken is $= 2s$

The formula for the average acceleration is given by,

$a_v_g = \frac{v_{f}-v_i }{t_f-t_i}$

⇒ $a_v_g = \frac{26.66-0}{2-0}$

⇒ $a_v_g=13.33m/s^{-2}$

Final answer:

The average acceleration of the cheetah is  $13.33m/s^{-2}$
