The person running towards the trumpet, Mr. C,
hears a higher frequency.

The person running away from the trumpet, Mrs. B,
hears a lower frequency.

The trumpeter, Mr. A, and the person who is just standing still
and listening, Miss D, both hears the beautiful perfect B-flat.

5. Find the mass of a car that is traveling at a velocity of 35 m/s West.
sattari [20]

Answer:

m = 9795.9 kg

Explanation:

v = 35 m/s

KE = 6,000,000 J

Plug those values into the following equation:

KE = \frac{1}{2} mv^{2}

6,000,000 J = (1/2)(35^2)m

---> m = 9795.9 kg
