The unstretched length of the cord is 0.500m and it's mass is 5.00g.The "spring constant" for the cord is 100N/m. Block is released and stops at lowest point.
a) determine the tension in cord when block is at lowest point.
I'm not sure but I do know that
Sum F= T-mg= 0 at lowest point.
but is the T= mg and that's it?
b) what is length of cord in stretched position?
I think but I'm not sure that I can find it by using
v= rad(T/mu)= rad(mgL/mblock)
However I don't think I can use this since I don't have v or L.
c) find speed of transversal wave in cord if block is at lowest position.
what I thought transverse speed was was from the equation:
vy= -omega*A cos(kx-omega*t) but I don't think I can use k that was given since It's not the same and I don't think I have omega either so how would I find transversal wave speed?
