Short Answer

Expert verified

The work done is $2714 J o u l e s .$

Step by step solution

Step 1. Given information.

The weight is $20 p o u n d s .$

The height is $100 f t .$

Step 2. Value of the Work.

We know,

$W = m g h W = 20 \times 0.454 k g \times 9.8 \times 100 \times 0.305 W = 2714.012$

Consider the region between the graph of $f (x) = x - 2$ and the x-axis on [2,5]. For each line of rotation given in Exercises 35– 40, use definite integrals to find the volume of the resulting solid.

Each of the definite integrals in Exercises 19–24 represents the volume of a solid of revolution obtained by rotating a region around either the x- or y-axis. Find this region.

$π \int_{1}^{3} (x^{2} - 2 x + 1) dx$

$\frac{d y}{d x} = 5 y, y (0) = 1$

Use antidifferentiation and/or separation of variables to solve each of the initial-value problems in Exercises 29–52.

34. $\frac{d y}{d x} = \frac{1}{y}, y (0) = 3$

Use antidifferentiation and/or separation of variables to solve each of the initial-value problems in Exercises 29–52.

32. $\frac{d y}{d x} = - 5 y, y (0) = 2$
