A particle moves along a line with acceleration a (t) = -1/(t+2)2 ft/sec2. Find the distance traveled by the particle during the

amm1812

Answer:

$s(t)=(ln|7|+ln|2|)\,ft$

Step-by-step explanation:

Acceleration is second derivative of distance and are related as:

$a(t)=\frac{d^2s}{dt^2}\\\\\frac{d^2s}{dt^2}=\frac{-1}{(t+2)^2}\\$

Integrating both sides w.r.to t

$v(t)=\frac{ds}{dt}=\frac{1}{t+2} +C\\$

Using initial value

$v(0)=\frac{1}{2}\\\\\frac{1}{2}=\frac{1}{0+2} +C\\\\C=0\\\\\frac{ds}{dt}=\frac{1}{t+2}$

We have to calculate the distance covered in time interval [0,5], so:

$\int\limits^5_0 \frac{ds}{dt}=\int\limits^5_0 {\frac{1}{t+2}} \, dt\\\\s(t)=[ln|t+2|]^5_0\\\\s(t)=ln|5+2|+ln|0+2|\\\\s(t)=(ln|7|+ln|2|)\,ft$

Find the x-intercept form the line represented by this equation. 5x+7y=3

krek1111 [17]

Answer:

A. (3/5, 0).

Step-by-step explanation:

The x intercept occurs where y = 0, so we have:

5x + 7(0) = 3

5x = 3

x = 3/5 so the required point is (3/5, 0).

What is the slope of (4,12) and (-8,2)

koban [17]

Answer:

Slope = $\frac{5}{6}$

Step-by-step explanation:

Slope = $\frac{y2 - y1}{x2 - x1}$

Slope = $\frac{2 - 12}{-8 - 4}$

Slope = $\frac{-10}{-12}$

Slope = $\frac{5}{6}$

Answer: Slope = $\frac{5}{6}$
