Solution please ASAP!!!

 

A particle moves in a straight line so that at time t its displacement from a fixed origin is x and its velocity is v. Its acceleration is 1 – 3t2 m/s- at any time t. The body is initially at x = 7 and its initial velocity is 11 m/s. Find the displacement of the particle at any time t. 15 marks]
