Question

a custodian pulls a vacuum 13.5 m with a 33.9 N force at a 55 degree angle, against a 14.1 N friction force. Find the work done by the custodian.

Answer 1

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

Step-by-step explanation:

Answer 2

262.49 (acellus answer is 262)

Step-by-step explanation:

Formula: Work= F x D Cos(degree

33.9 * 13.5 = 457.65

457.65 Cos(55 = 262.49

Hope this helps
