To calculate the displacement, we have to break down the movement into totally different intervals and calculate the displacement for every interval. We are able to then add up the displacements for every interval to get the whole displacement.
The displacement for the primary interval is:
displacement (0-2) = velocity (0-2) * time (0-2) = 10 m/s * 2 s = 20 m
The displacement for the second interval is:
displacement (2-4) = velocity (2-4) * time (2-4) = 20 m/s * 2 s = 40 m
The displacement for the third interval is:
displacement (4-6) = velocity (4-6) * time (4-6) = 30 m/s * 2 s = 60 m
The overall displacement is:
displacement (whole) = displacement (0-2) + displacement (2-4) + displacement (4-6) = 20 m + 40 m + 60 m = 120 m
The reply is 120 m.
