Answer:
(4) The particle travels with a constant velocity until t0 and then comes to rest.
Explanation:
Uniform rectilinear motion is defined as the motion of a particle in a straight line with constant velocity, that is, there is no change in velocity over time.
And this can be determined by means of the following equation:
[tex]x=x_{o}+v*(t-t_{o})[/tex]
where:
x = final point [m]
xo = initial point [m]
v = velocity (slope) [m/s]
t = final time [s]
to = initial time [s]
So the slope in the graph gives the constant velocity
[tex]v=\frac{x-x_{o}}{t-t_{o}}[/tex]
Therefore, after the time to there is no displacement, that is the particle comes to rest.
