Two particles move in the same direction , passing a point A when velocity of P = 10-2t and velocity of Q = 6t(t-3). For 1≤t≤5.
i) Sketch velocity time graph for both particles
ii) show that both the particles meet at t=5
iii) what is the maximum distance between the particles between t = 1≤t≤5
Please if someone could solve the last part.
