Two objects start from the same point and move in the same direction for 6.0 s.
Object P accelerates uniformly from rest to 10 m/s during the first 4.0 s, then continues at 10 m/s for 2.0 s.
Object Q travels at a constant velocity of 8.0 m/s throughout.
Which statement describes their positions after 6.0 s?
P is 8.0 m8.0\ \mathrm{m}8.0 m ahead of Q.
Q is 8.0 m8.0\ \mathrm{m}8.0 m ahead of P.
P is 12 m12\ \mathrm{m}12 m ahead of Q.
Q is 12 m12\ \mathrm{m}12 m ahead of P.
