Like usual I have a few questions I can't do.
1. Given that x = asin(nt+α), find v as a function of time (<--this part i can do). Find a, n and α if a>0, n>0, 0≤α<2pi and:
a) the period is 6 seconds, and initially x=0 and v=5.
2. Particle moving in S.H.M. has period pi/2 seconds. Initially the particle is at x=3 with velocity v=16m/s.
a) Find x as function of t in form x = bsin nt + c cosnt (<-- i was able to do this)
b) Find x as a function of t in the form x = acos(nt-ε), where a>0 and 0≤ε<2pi.
Cheers.
