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

$s = 14.33 \times 3 = 43 m$

now from above formula of work done we will say

$W = 848 \times 43$

$W = 36464 J$

so above is the work done to move three corridors
