Answer:
a) initial position = 10m
b) average velocity = 30m/s
Explanation:
The general equation of a motion with constant velocity is given by:
[tex]S(t)=S_o+vt[/tex] (1)
So: initial position
v: average velocity
t: time
You have the following equation:
[tex]S(t)=10+30t[/tex] (2)
If you compare the equations (1) and (2) you obtain that:
[tex]S_o=10m\\\\v=30\frac{m}{s}[/tex]
hence:
a) initial position = 10m
b) average velocity = 30m/s
