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

          Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

A) Let's solve for x.  2x + 3y = 40

Step 1: Add -3y to both sides.

2x + 3y + -3y = 40 + -3y

2x = -3y + 40

Step 2: Divide both sides by 2.

\frac{2x}{2} = \frac{-3y + 40}{2}

x = \frac{-3}{2} y + 20

Answer : \frac{-3}{2} y + 20

~~~~~~~~~~~~~~~~~

B) Let's solve for x. 5x + 2y = 30

Step 1: Add -2y to both sides.

5x + 2y + -2y = 30 + -2y

5x = -2y + 30

Step 2: Divide both sides by 5.

\frac{5x}{5} = \frac{-2y + 30}{5}

x = \frac{-2}{5} y + 6

Answer : \frac{-2}{5} y + 6
