My teacher gave us lots of exercise without answer and help i feel so frustrated to complete all those exercise but i can't answer any of them. i search in the book and i can't find anyway suitable way for that question. this question is very simple but i can't get a away to answer it. please help.

1)A body describing simple harmonic motion has a maximum acceleration of 8pie m/s2 and a maximum speed of 1.6 m/s. find the period T and the amplitude R

2)A size is swinging in a horizontal circle 0.8m in diameter, at 30rev/min. A distant light causes a shadow if the stone to be formed on a nearby wall. what is the amplitude of the motion of the shadow? what is the frequency? what is the period?

3)a body executes SHM with an amplitude of 2.00cm and a frequency of 3.00Hz. At t=0s, the displacement is x(0)=0cm and the velocity v(0) is positive.

(a) Obtain analytical expressions for the displacement x(t), the velocity v(t), the acceleration a(t)

(b)evaluate the expressions found in part (a) for t=50ms

anyone who is concern to help me can also add me at msn suding_junix@hotmail.com

your help in solving this questions is highly appreciated thanks...
