Answer:
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,
[tex]v=\dfrac{(8-0)\ m}{(16-0)\ s}\\\\v=0.5\ m/s[/tex]
So, the skater's average velocity from t= os to t= 16s is 0.5 m/s.
