Homework Statement
Algebra based physics: A 23 kg mass is suspended from the bottom of a rope of length 2.4 m and mass 17 kg. The acceleration of gravity is 9.8 m/s^2.
Find time for a transverse wave to travel the length of the rope. Answer in units of sec.
Homework Equations
u= mass rope/ length rope
F=mg
v= d/t
The Attempt at a Solution
u= 17kg / 2.4m = 7.0833333
v= sqr (17+23)(9.8)/7.0833333
v= 7.439165039
t= d/v
t= 2.4m / 7.439165039
t= 0.322616851 s
This answer is wrong and I've had 2 tutors look over this but couldn't figure where the problem is.
