Given data:

* The initial velocity of the rabbit is u = 0 m/s.

* The acceleration of the rabbit is,


a=7.5ms^(-2)

* The time taken is t = 3 s.

Solution:

By the kinematics equation, the final velocity of the rabbit is,


v-u=at

Substituting the known values,


\begin{gathered} v-0=7.5*3 \\ v=22.5\text{ m/s} \end{gathered}

Thus, the velocity of the rabbit is 22.5 m/s.
