Question

A 4 pound force acting in the direction of (4,-2) moves an object just over 7 ft from point (0,4) to point (5,-1). Find the work done to move the object to the nearest foot-pound

Answer 1

Answer:

$W=59.7408J$

Step-by-step explanation:

From the question we are told that:

Force $f=4N$

Force Direction $\arrow (4,-2)$

Distance traveled $d_t=7ft \aprrox\ 2.1336m$

Distance traveled Direction point (0,4) to point (5,-1)

 

Generally the equation for work done is mathematically given by

 $W=force*distance$

 $W=f*d_t\\W=4*7*2.1336$

 $W=59.7408J$
