1. The problem statement, all variables and given/known data Please find the question in the attachment,i've attached it because it includes a graph 2. Relevant equations a=-(omega)^2.x T=2.pie/omega Vmax=omega.A 3. The attempt at a solution for part b i used the first equation a=-(omega)^2.x to find omega and then substituted the value of omega in the second equation mentioned above. a=-(omega)^2.x omega=*sqrt*a/x omega = 1.5/10 omega=0.39 and thus T=1.6 m/s Please tell me if i'm right so far? for part c i can use the third eq but i can't figure out how to find the amplitude?
