Determine the frequency and the wavelength experience by a stationary observer, when b) the truck is approaching the observer.

c) the truck is moving away from the observer.

d) the beat frequency if the observer hears the signal from a truck approaching and the signal from a trucking moving away at 25m/s,

e) the average frequency from part (c).

An atomic nucleus initially moving at 420m/s emits an alpha particle in the direction of its velocity, and the new nucleus slows to 346m/s. If the alpha particle has a mass of 2u and the original nucleus has a mass of 222u, what speed does the alpha particle have when it is emitted? I need a final correct answer in order to give full rating.
