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.
In a completely inelastic collision, the two objects stick together after the collision.

From the data in the given table, it can. be concluded that the angle of refraction decreases with increasing wavelength.
<h3>What is wavelength of light wave?</h3>
The wavelength of a wave is the distance between two successive points on the wave.
The wavelength of a wave is usually measured in metres.
The angle of refraction is the angle to which a wave is bent from the normal.
The color of light that has the shortest wavelength is Red while violet has the longest wavelength.
From the table provided, it can be seen that the angle of refraction decreases with increasing wavelength.

3,89,988 cm/min is the linear velocity
Given,
Diameter of CD = 12 cm
So, Radius of CD = 6 cm
CD is spinning at 10350 rev/min
Firstly , convert rev/min into rad/min
1 rev = 2π radians
10350 rev/min = 10350 × 2π
= 64998 rad/min
Formula used,
where,
is the Linear velocity
is the radius
is the angular velocity
= 6 cm × 64998rad/min
= 3,89,988 cm/min
Thus, linear velocity for any edge point of a 12-cm-diameter CD (compact disc) spinning at 10,350 rev/min is 389988 cm/min.
