Find the work done by the force field F(x, y) = xi + (y + 5)j in moving an object along an arch of the cycloid r(t) = (t − sin(t

Nimfa-mama [501]

Integrate the force field along the given path (call it C):

$W=\displaystyle\int_C\mathbf F(x,y)\cdot\mathrm d\mathbf r=\int_0^{2\pi}\mathbf F(x(t),y(t))\cdot\frac{\mathrm d\mathbf r}{\mathrm dt}\,\mathrm dt$

$=\displaystyle\int_0^{2\pi}\bigg((t-\sin t)\,\mathbf i+(6-\cos t)\,\mathbf j\bigg)\cdot\bigg((1-\cos t)\,\mathbf i+\sin t\,\mathbf j\bigg)\,\mathrm dt$

$=\displaystyle\int_0^{2\pi}(t-t\cos t+5\sin t)\,\mathrm dt=\boxed{2\pi^2}$

your heart pumps about 5 quarts of blood through its chamber every 60 seconds. a swimming pool, holds 65,000 gallons of water. t

Semmy [17]

First, we find out how many quarts of water is in a swimming pool, so we do the following:
$65000 gallons * \frac{4 quarts}{1 gallon} = 260000 quarts$

And since we know the heart pumps 5 quarts of blood per 60 seconds, and there is a total of 260000 quarts to pump, we can find the amount of time it takes to pump the blood by doing the following:

$260000 quarts * \frac{60 seconds}{5 quarts} = 3120000 seconds$

so now we know that it takes 3120000 seconds to pump the blood. All that is left is find out how many weeks is equal to 3120000 seconds, so we do the following:
 $3120000 seconds * \frac{1 week}{604800 seconds} = 5.16 weeks$

So the answer is approximately 5.16 weeks
