Answer:
2 m uphill
Step-by-step explanation:
The displacement can be calculated as the difference between the final position and the initial position.
In this case, the initial position is 0 m
And the final position is
6 m - 4m = 2 m
Because the ball rolled 6 m uphill and then 4 m downhill.
Then, the displacement is equal to
Displacement = Final position - Initial position
Displacement = 2 m - 0 m
Displacement = 2 m
Therefore, the total displacement of the ball is 2 m uphill
