An object is sliding to the right along a straight line on a horizontal surface. The graph shows the object's velocity as a function of time. What is the object's displacement during the time depicted in the graph?

Explanation:

Velocity is the change of displacement of a body with respect to time.

Velocity = Displacement/Time

Displacement = Δv * Δt

From the graph, it can be seen that the object sliding along the horizontal has a velocity of 0m/s since it starts travelling when v = 0m/s

For the time;

Δt =t2-t1

Δt = 8-0

Δt = 8s

object's displacement = 0 * 8

Hence the object displacement is 0m
