Final answer:

The bicyclist traveled approximately 18.7 meters during the given time.

Step-by-step explanation:

To find the distance traveled by the bicyclist, we can use the equation:

distance = initial velocity × time + (1/2) × acceleration × time²

Given:

Initial velocity (u) = 0 m/s (starting from rest)Final velocity (v) = 11.0 m/sTime (t) = 3.40 s

Acceleration (a) = ? (to be found)

We can rearrange the equation to solve for acceleration:

distance = 0 × time + (1/2) × acceleration × time²

distance = (1/2) × acceleration × time²

Plugging in the given values, we get:

distance = (1/2) × acceleration × (3.40 s)²

Simplifying further:

distance = (1/2) × acceleration × 11.56 s²

Since we are looking for distance, we need to solve for acceleration:

acceleration = (2 × distance) / (time²)

Plugging in the given values, we get:

acceleration = (2 × distance) / (3.40 s)²

Now we can solve for acceleration:

acceleration = (2 × distance) / 11.56

Given that the final velocity is 11.0 m/s, we can use the equation:

final velocity = initial velocity + acceleration × time

Plugging in the given values, we get:

11.0 m/s = 0 m/s + acceleration × 3.40 s

Now we can solve for acceleration:

acceleration = 11.0 m/s / 3.40 s

Finally, we can substitute the value of acceleration back into the equation for distance:

distance = (2 × (11.0 m/s / 3.40 s)) / 11.56

Calculating this expression, we find that the distance traveled by the bicyclist during the given time is approximately 18.7 meters.
