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.

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:

262.5 J

Explanation:

w=(f)(d)cos(angle

w=33.9)(13.5)cos(55

w=262.5 J

this is the right answer

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
