A 46.5-kg ball has a momentum of 57.2 kg m/s. What is the ball's speed?
Serhud [2]

Answer:

1.23 m/s

Explanation:

p=mv

57.2 = 46.5v

v= 57.2/46.5

v= 1.23

If you want to verify your answer, just insert the value of v in the equation.

Unpolarized light with an average intensity of 845 W/m2 enters a polarizer with a vertical transmission axis. The transmitted li
RideAnS [48]

The concept to develop this problem is the Law of Malus. Which describes what happens with the light intensity once it passes through a polarized material.

Mathematically this can be expressed as

I = I_0 cos^2\theta

Where

I = New intensity after pass through the Polarizer

I_0= Original intensity

\theta = Indicates the angle between the axis of the analyzer and the polarization axis of the incident light.

When the light passes perpendicularly through the first polarizer, the light intensity is reduced by half which will cause the intensity to be 225W / m ^ 2 at the output of the new polarizer, mathematically:

I= \frac{I_0}{2} cos^2\theta

225 = \frac{845}{2}cos^2\theta

Solving to find the angle we have

\theta = 43.11\°

The orientation angle of the second polarizer relative to the first one is 43.11°
