Answer:
Momentum, p = mv
Explanation:
The momentum of an object gives the relation between mass when it is in motion. It is given by the relation as follows :
Where
m is the mass of the object
v is the speed of the object
It is clear that the correct option is (A) "p = mv". Hence, this is the required solution.
Answer
79.8 miles per hours fast is the car going.
Formula
By using the dopplers effect. (When source is approching .)
As given
A car approaches you with its horn blowing.
The observed frequency is 503.7 Hz.
The speed of sound is 1100 ft/s .
The car's horn has a frequency of 450 Hz.
i.e
v = 1100 ft/s
Put in the above formula
Now convert 117.3 ft per second into miles per hours.
117.3 feet per second = 79.8 miles per hours (Approx)
Thus
Therefore the 79.8 miles per hours fast is the car going.
Rate of speed (3 m/s north is three miles per second north, so it's a rate of speed)
