## 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.
