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

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

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