Find an expression in terms of M, mu, and theta for the speed of waves on the string.Express your answer in terms of the variables M, mu, theta, and appropriate constants.

Question

The picture shown is just of a block with mass m on an inclined frictionless surface at angle theta. the block is attached to a string with density mu.

Answer 1

v=sqrt((Mgsin(theta))/mu)

Answer 2

There is no lowercase m in the denominator.

Answer 3

mu is the name representation for the u with the little bit in front, hence large M is used for mass to reduce confusion
