Determine the skater's average velocity from t= os to t= 16s. (average velocity is the displacement (final position minus initial position) divided by time elapsed.)

v = 0.5 m/s

Explanation:

The attached figure shows Robin's positions wrt time who is rollerskating down a marked side walk.

We need to find the skater's average velocity from t= os to t= 16s.

Average velocity = displacement/time

Displacement = final postion - initial position

Displacement = (8 - 0) m/s

Displacement = 8 m/s

Time, t = (16 - 0) s

So,

So, the skater's average velocity from t= os to t= 16s is 0.5 m/s.
