An object start from rest at the orgin and moves along the x axis a constant of4 m/ s it's average two x =8m is ____
To find the average velocity, we can use the formula:
Average velocity = change in position / change in time
In this case, the object starts from rest at the origin (x = 0) and moves along the x-axis with a constant velocity of 4 m/s. We want to find the average velocity for the interval from x = 0 to x = 8 m.
Change in position = x_final - x_initial = 8 m - 0 m = 8 m
Change in time is the time it takes for the object to move from x = 0 to x = 8 m.
To find the time, we can use the formula:
Distance = velocity * time
Since the object moves with a constant velocity of 4 m/s, and the distance traveled is 8 m, we can rearrange the formula to solve for time:
time = distance / velocity = 8 m / 4 m/s = 2 s
Now we have the change in position (8 m) and the change in time (2 s). Plugging these values into the formula for average velocity:
Average velocity = change in position / change in time = 8 m / 2 s = 4 m/s
Therefore, the average velocity for the interval x = 0 to x = 8 m is 4 m/s.
