Find the work done by force dield f(x,y)=x^2i+ye^xj on a particle that moves along parabola x=y^2+1 from(1,0) to (2,1)

NemiM [27]

Call the parabola $P$ , parameterized by $\mathbf r(y)=\langle y^2+1,y\rangle$ with $0\le y\le 1\rangle$ . Then the work done by $\mathbf f(x,y)$ along $P$ is

$\displaystyle\int_P\mathbf f(x,y)\cdot\mathrm d\mathbf r=\int_{y=0}^{y=1}\mathbf f(x(y),y)\cdot\dfrac{\mathrm d\mathbf r(y)}{\mathrm dy}\,\mathrm dy$
$=\displaystyle\int_0^1\langle(y^2+1)^2,ye^{y^2+1}\rangle\cdot\langle2y,1\rangle\,\mathrm dy$
$=\displaystyle\int_0^1(2y^5+4y^3+2y+ye^{y^2+1})\,\mathrm dy=\frac73-\frac e2+\frac{e^2}2$

HIGH SCHOOL MATH ....

umka21 [38]

Answer:

The value of $B (base\ area) = 27m^2$

Step-by-step explanation:

Let's recall the the formula for volume of a pyramid.

Volume of a Pyramid $= \frac{1}{3}\times B\times H}$ ....equation $(1)$

where $B=Base\ area (m^2)$ and $H=height\ (m)$

Now we have been given the values of $V$ and $H$ and have to find the value of $B$

Plugging the values of $V$ and $H$ in equation $(1)$

$B=\frac{3\times V}{H}= \frac{3 \times 81}{9} = 27\ m^2$

Now we can also check our previous results.

$V = \frac{24\times 7}{3}=8 \times 7 =56\ m^3$

So, our final answer is $27\ m^2$
