Question (i) is the most difficult.
Question (ii) is easy since greatest speed will be achieved when P passes at its equilibrium position. Value of speed is more complicated.
Finding actual position for greatest acceleration in question (iii) is pretty obvious. For value of acceleration, work out the net force acting on P. I find 40 m/s²
