Two particles P and Q move towards each
other along a straight line MN, 51 meters
long. P starts fromM with velocity 5 ms^(−1)
and constant acceleration of 1 ms^(−2) . Q starts
from N at the same time with velocity 6 ms^(−1)
and at a constant acceleration of 3 ms^(−2) .
Find the time when the:
(a) particles are 30 metres apart;
(b) particles meet;
(c) velocity of P is (3/4) os the velocity of Q.
