Question

Find the work done by a force of 200 pounds acting in the direction in moving an object 75 feet from (0, 0) to (-75, 0).

Answer 1

To find the work done by a force of 200 pounds in moving an object 75 feet, you can use the formula Work = Force * Distance. First, convert pounds to Newtons and feet to meters. Then, multiply the force and distance to get the work done in Joules.

Step-by-step explanation:

To find the work done by a force, you can use the formula:

Work = Force * Distance

In this case, the force is 200 pounds and the distance is 75 feet. However, we need to convert pounds to Newtons, since the formula requires Newtons as the unit of force. 1 pound is approximately equal to 4.45 Newtons. So, 200 pounds is equal to 200 * 4.45 = 890 Newtons. The distance is 75 feet, which is equivalent to 75 * 0.3048 = 22.86 meters.

Now we can calculate the work:

Work = 890 N * 22.86 m = 20329.4 Joules

Answer 2

Answer:
`15000\ lbf.ft`

Step-by-step explanation:

Given

Force acting is
`200\ Pounds`

The direction of action is from
`(0,0)\ to\ (-75,0)`

Work done is given by

`W=F\cdot ds`

As the displacement occurs in the x-direction

`\therefore W=200\cdot 75\\\Rightarrow W=15000\ lbf-ft`
