Unsure of what steps to take when approaching this kinematics question.Watch
where x is measured in metres.
Find the distance that the particle has traveled after 4 seconds.
the displacement after 4s is 0m but not the total distance. As the graph is a perfect parabola, find the distance travelled at the halfway point (2s) to find that as 4m and then double that for the total distance: 8m.
