b) Average velocity: 5.2 m/s
c) Average velocity: 7.6 m/s
Explanation:
a)
The position of the car as a function of time t is given by
where
The average velocity is given by the ratio between the displacement and the time taken:
The position at t = 0 is:
The position at t = 2.00 s is:
So the displacement is
The time interval is
And so, the average velocity in this interval is
b)
The position at t = 0 is:
While the position at t = 4.00 s is:
So the displacement is
The time interval is
So the average velocity here is
c)
The position at t = 2 s is:
While the position at t = 4 s is:
So the displacement is
While the time interval is
So the average velocity is
