The cyclist is moving by uniformly accelerated motion, with an initial velocity of
and an acceleration of
.
The acceleration is given by
where
is the final velocity and
is the time between the end and the beginning of the motion, and in our case it is 1.75 s. Therefore, from this relationship we can find the final velocity:
