The discussion revolves around calculating the speed of sound in air based on an echo heard after a clap, with specific measurements provided for distance and time. The subject area is primarily related to kinematics and acoustics.
Some participants have provided guidance on the calculation, noting the need to consider the total distance for the echo. Multiple interpretations of the problem are being explored, particularly regarding the distance the sound travels.
Participants are working under the assumption that the echo reflects off a cliff, which affects the total distance sound travels. There is also a reference to typical values for the speed of sound in air under atmospheric conditions.
What is the total distance the sound has to travel between the moment she claps her hand and the moment she hears the echo?Sace Ver said:Homework Statement
A student stands 86m from the foot of a cliff, claps her hands, and hears the echo 0.50s later. Calculate speed of sound in air.
Known
•86m
•0.50s
Homework Equations
V=331.4+0.606T
The Attempt at a Solution
V=d/t
V=86m/0.50s
V=172m/s
Is that the first step to the problem? If so I'm not quite sure what the next step is.

86m x 2 = 172 bc it is an echo?stockzahn said:Your formula is correct, but the value of the distance you used isn't.
