15. The base of a prism

storchak [24]

Answer:

Part a) $SA=458.4\ cm^2$

Part b) Added only one side triangular face instead of three side triangular faces

Step-by-step explanation:

we know that

The surface area of a triangular prism is equal to two times the area of the base plus the area of its three triangular faces

$SA=2(73.2)+3(104)$

$SA=146.4+312$

$SA=458.4\ cm^2$

Riley's error was

$SA=2(73.2)+(104)=250.4\ cm^2$

added only one side triangular face instead of three side triangular faces

A weight is suspended from a spring and is moving up and down in a simple harmonic motion . At start , the weight is pushed up 1

Ainat [17]

The weight is 11.651 centimeters <em>above</em> the resting position.

<h2>Procedure - Postion formula for a weight under simple harmonic motion</h2>

<h3>Simple harmonic motion model</h3>

Mathematically speaking, a simple harmonic motion is described by the following formula:

$y = A\cdot \cos \left(\frac{2\pi\cdot t}{T}) + y_{o}$ (1)

Where:

$t$ - TIme, in seconds.
$T$ - Period, in seconds.
$A$ - Amplitude, in centimeters.
$y_{o}$ - Resting position, in centimeters.

<h3>Current position of the weight with respect to the resting position</h3>

Please notice that the period is the time needed by the weight to complete one cycle. If we know that $A = 12\,cm$ , $y_{o} = 0\,cm$ , $T = 26\,s$ and $t = 25\,s$ , then the current position of the weight is:

$y = 12\cdot \cos \left(\frac{2\pi\cdot 25}{26} \right)+0$

$y = 11.651\,cm$

The weight is 11.651 centimeters <em>above</em> the resting position. $\blacksquare$
