\

The velocity of a flea $\"\"$ s jump is given by $\"\"$ .

\

Where $\"\"$ is time in seconds and velocity, $\"\"$ is $\"\"$ .

\

(a).

\

Find the anti derivative of $\"\"$ to find $\"\"$ .

\

Power rule of the integrals: $\"\"$ .

\

$\"\"$ .

$\"\"$

\

Substiute $\"\"$ and $\"\"$ and solve for $\"\"$ .

\

$\"\"$

\

Therefore $\"\"$ .
