please help me answer this. please answer on an ipad or piece of paper step by step.

A m= ousng , n= 550N/ m, x= 10.35 m A mass of 45 grams is attached to a spring with a constant of 550 N/m, as in the problem above. It is displaced to 35 cm and allowed to oscillate a) What is the total energy of this system? b) At what point(s) is K at a maximum and Us at a minimum? c) At what point(s) is Us at a maximum and K at a minimum? d) Find the speed of the mass when x = 20 cm. 0-dom e) Find x when the K is equal to TWICE the Us f) Find x when K is equal to HALF the Us
