the frequency is greater than 250 Hz the beats at 250 means you are close, and if the beats increase as you lower the frequency, that means you are going in the wrong direction.
CoM of system has velocity Vcm = 1u*472m/s / 15u = 31.5 m/s For an elastic, head-on collision, we know (from conservation of energy), that the relative velocity of approach = relative velocity of separation, or 472 m/s = V - U where V is the post-collision velocity of the nucleus and...

(A) Work = force × distance Power = work/time 1,200kg × 9.8N/kg × 1,000m = 11.76 MegaNewtons 11.76×10^6/3.6×10^3 = 3.267kW 3.267kW/.746 = 4.38 HP (B) Frictional losses (air resistance, rolling resistance...

Depends on what you mean by "if drawn as a wave." If the two instruments are playing the same C (that is, they are in the same octave), and the wave represents only the primary wavelength associated with that frequency, then...
Well, you definitely hear beats with a frequency of 5 per second (e). You would probably also claim to hear dissonance (a).
