What is the momentum of a bus that weighs 13,500,000 grams traveling at 65 mph?

Goryan [66]

The momentum of the bus is $3.93\cdot 10^5 kg m/s$

Explanation:

The momentum of an object is given by

$p=mv$

where

m is the mass of the object

v is its velocity

For the bus in this problem, we have

$m=13,500,000 g = 13,500 kg$ is its mass

$v=65 mph \cdot \frac{1609 m/mi}{3600 s/h}=29.1 m/s$ is the velocity, converted into SI units

Substituting into the equation, we find the momentum of the bus:

$p=(13,500)(29.1)=3.93\cdot 10^5 kg m/s$

Example: What power of spectacle lens is needed to correct the vision of a nearsighted person

Aleksandr [31]

<h3>Concave or diverging lens is needed correct the vision of a nearsighted person whose far point is 30.0 cm</h3>

<em><u>Solution:</u></em>

Nearsighted person will not be able to see the distant objects clearly

Now, we want the near sighted person to see the distant objects clearly

<em><u>The lens equation is given as:</u></em>

$P = \frac{1}{d_o} + \frac{1}{d_i}$

For distant vision, $d_0 = \infty$

$d_i = image\ distance\\\\d_0 = lens\ to\ retina\ distance$

The image of 30 cm from eye will be 28.5 cm to left of spectacle lens

Therefore,

$d_i = -28.5\ cm = 0.285\ meter$

From lens equation,

$P = \frac{1}{ \infty } + \frac{1}{-0.285\ meter}\\\\P = 0 - 3.51 \\\\P = -3.51\ diopter$

The negative power -3.51 D denotes that a concave or diverging lens is needed
