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

`W=59.7408J`

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`
