1. The problem statement, all variables and given/known data A hooter on a motorcycle sounds a note of 6000Hz when the motorcycle is stationary. You detect a shift in frequency of 30Hz when the motorcycle approaches you and then recedes from you. Calculate the speed of the motorcycle. Speed of sound = 340m/s 2. Relevant equations fl = fs(v/v-vs) 3. The attempt at a solution When motorcycle approaches: fl = (v/v-vs) 6030 = (340/340-vs) vs = 16.58m/s When motorcycle recedes: fl = (v/v+vs) 5070 = (340/340+vs) vs = 54.48m/s Is this correct?
