Homework Statement
A tuning fork vibrating at 506 Hz falls from rest and accelerates at 9.80 m/s2. How far below the point of release is the tuning fork when waves of frequency of 488 Hz reach the release point? (Take the speed of sound in air to be 343 m/s).
Homework Equations
f(prime)=(v/(v+v(source)))*f(initial)
x=v(source)^2/19.6
The Attempt at a Solution
im actually fairly happy with my answer (8.17), because i worked it backwards from a textbook question, after it said i was wrong. but the system says i was wrong ( but within 10 percent).
any insight?
btw i subbed in my value for v(source) from question 1 into question 2 to get my answer.
