Answer:

W=FD

W=33.9(13.5) this is asking for work done by custodian so you disregard friction force that will change the velocity and such but not the work the custodian does.

W=458

It is possible I am wrong but I believe this to be correct

Explanation:

Answer:

262.49 (acellus answer is 262)

Explanation:

Formula: Work= F x D Cos(degree

33.9 * 13.5 = 457.65

457.65 Cos(55 =  262.49

Hope this helps
