particles p and Q leave a fixed point A at the same time and travel in the same straight line. the velocity of P after t seconds is 6t(t-3)ms-1 and the velocity of Q after t seconds is (10-2t)ms-1.
1) sketch,on the same axes, velocity-time graph for P and Q for 0<=t<=5
2)verify that P and Q meet after 5 seconds.
3)find the greatest distance between P and Q for 0<=t<=5
