Given:

The acceleration of the dolphin is


a=1.77\text{ m/s}^2

The time taken by the dolphin is


t=3.33\text{ s}

The velocity of the dolphin at the end is


v=8.77\text{ m/s}

Required: the displacement of the dolphin

Explanation:

The displacement of the dolphin can be calculated by the third equation of motion. that is given by


s=ut+(1)/(2)at^2

we assume that the initial velocity of the dolphin is zero u=0.

plugging all the values in the above equation, we get


\begin{gathered} s=0*3.33\text{ s+}(1)/(2)*1.77\text{ m/s}^2*(3.33\text{ s})^2 \\ s=9.81\text{ m} \end{gathered}

Thus, the displacement of the dolphin is


9.81\text{ m}
