Answer:
C.) v = 50 m/s
Explanation:
The relationship between position vs. time graph and velocity is that the derivative (slope) of the position vs. time graph gives you velocity. In other words, find the slope to get the velocity.
Select two arbitrary points. I'll choose (3s, 225m) and (0s, 75m).
Now use the slope equation:
[tex]v = \frac{y_{2} - y_{1} }{x_{2} - x_{1}} =\frac{225 - 75}{3-0} = 50 m/s[/tex]
v = 50 m/s
Hopes this helps!
