Maths as Edexcel kinematics help pls

At time seconds, the velocity of a particle P is [(47 - 7)1 - 51] m s1. When = 0, P is at thepoint with position vector (3i 5j) m relative to a fixed origin 0.(a)Find an expression for the position vector of P after t seconds, giving your answer in the form (ai bj) m(4)A second particle O moves with constant velocity (2i - 3j) m s1. When = 0, the positionvector of O is (-7i) m(b) Prove that P and O collide.
