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:
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
Therefore, after the time to there is no displacement, that is the particle comes to rest.

Answer:
well at the rate he goes he would be at 2.5km
Answer:
R1 + R2 = R = 12 for resistors in series - so R1 = R2 if they are identical
2 R1 = 12 and R1 = R2 = 6 ohms
1 / R = 1 / R1 + 1 / R2 for resistors in parallel
R = R1 * R2 / (R1 + R2) = 6 * 6 / (6 + 6) = 3
The equivalent resistance would be 3 ohms if connected in parallel
