Now let’s apply our definition of average velocity to a swimming competition. During one heat of a swim meet, a swimmer performs the crawl stroke in a pool 50.0 mm long, as shown in (Figure 1). She swims a length at racing speed, taking 24.0 ss to cover the length of the pool. She then takes twice that time to swim casually back to her starting point. Find (a) her average velocity for each length and (b) her average velocity for the entire swim.
c) If the swimmer could cross a 15 kmkm channel maintaining the same average velocity as for the first 50 mm in the pool, how long would it take?
The position of a particle in millimeters is given by s = 27 – 12t + t, where t is in seconds. Plot the s-t

A traveling object might move at different speeds and in different directions during an interval of time, but if we ask at what constant velocity the object would have to travel to achieve the same displacement over the given time interval, that is what we call the object's average velocity.
