Question

You are a nurse in a hospital. You are told to move a patient through three corridors each measuring 14.33 meters. Because of friction it requires a constant force of 848 N to move the patient and wheelchair. How much work must you perform to accomplish this task?

Answer 1

Work done by force is given by formula

`W = F.d`

now here work done against friction is given so force of friction here is

`F_f = 848 N`

It moved by three corridors with each measures

`d = 14.33 m`

so total distance will be

`s = 14.33 * 3 = 43 m`

now from above formula of work done we will say

`W = 848 * 43`

`W = 36464 J`

so above is the work done to move three corridors
