Answer:
d) -2.0 m/s
Explanation:
Time taken by the man is 5.5 seconds
Final position = -1 m = [tex]x_f[/tex]
Initial position = 10 m = [tex]x_i[/tex]
Total distance covered
[tex]\Delta x=x_f-x_i\\\Rightarrow x=-1-10=-11\ m[/tex]
Velocity = Distance / Time
[tex]v=\frac{-11}{5.5}\\\Rightarrow v=-2\ m/s[/tex]
∴ Person's average velocity is -2m/s
