For the first part you need this
You know k and m (watch out for the units in k) so can work out the angular frequency.

Then fr the second bit, you should have, either in formula list, notes, or text book, an equation which tells you how to find the max velocity if you know the amplitude and the angular frequency.
For the last two parts these equations are useful (sorry, can't see the buttons anymore to include images, try here http://ibguides.com/images/formula_1.png
The 4th one will help you with th 3rd part.
For the final part, look at the 1st and third equations. They both contain sin(wt) so in otherwords, a = -w²x which means you can also find the acceleration.
I CANNOT STRESS ENOUGH THE IMPORTANCE OF LOOKING FOR THESE EQUATIONS IN YOUR BOOK AND ESPECIALLY ON THE FORMULA SHEET YOU WILL HAVE IN THE EXAM to see exactly in what form they are given and how you would use them
