Another SHM question. Thanks for the help on my first one.
The block is at x0 = +5 cm with a positive velocity V0 at time t = 0. Its motion is SHM with amplitude 10 cm and period 2 seconds. If x(t) = Acos(wt + [tex]\varphi[/tex]), the phase constant [tex]\varphi[/tex] should be:
x(t) = Acos(wt + [tex]\varphi[/tex])
The Attempt at a Solution
0.05 = 0.10cos([tex]\pi[/tex] + [tex]\varphi[/tex])
[tex]\varphi[/tex] = 60 - [tex]\pi[/tex] (since the 60 is in degrees...do I just use pi radians = 3.14 radians?)
= 57 degrees
I got the pi for wt this way btw:
wT = 2pi
w = 2pi/T = pi (since T = 2)
Not sure if I screwed up that or the radians/degrees thing at the end. Any help would be appreciated.
