When a car hits you in a rear end collision, the car initially has a momentum going in one direction. This causes your car to move in the same direction that car was moving even if you were at rest. So, for conservation of momentum, you initially have momentum going in the east direction for example, after the collision, you will have a change in momentum which causes you to have a velocity in the west direction. This is because you are initially at rest and then there is a sudden change in velocity so when you speed up, that momentum causes you to move backwards. If you don't have a properly adjusted neckrest you could may experience whiplash.

A full lake is dropping at its constant rate, meaning it is unchanging over time.
After 4 weeks’ time, it already dropped 3 feet.
Now, let’s solve for the Unit rate based on the given data.
=> 3 feet in 4 weeks
=> Unit rate is 3 feet per 4 weeks
=> in 4 weeks there are (7 * 4) = 28 days
=> 3 feet / 28 days
=> the Unit rate is .107 feet / day
Answer:
Explanation:
6 waves in 12 seconds
The period of a wave is defined as the time taken by the wave to complete one oscillations.
Here, 6 waves are completed in 12 seconds
So, one wave is completed in 2 seconds
So, the period of the wave is 2 second.
frequency is defined as the number of waves completed in one second. It is the reciprocal of period of the wave.
frequency = 1 / 2 = 0.5 Hertz
Let the wavelength is λ.
f = 660 kHz = 660000 Hz
the relation for the wave speed and the wavelength and the frequency is given by
v = f λ
where v is the speed of wave = 3 x 10^8 m/s
So, 3 x 10^8 = 660000 x λ
λ = 454.55 m
