Physics Homework Problem
Julie has been hired to help paint the trim of a building, but she is not convinced of the safety of the apparatus. A 4.9 m plank is suspended horizontally from the top of the building by ropes attached at each end. She knows from previous experience that the ropes being used will break if the tension exceeds 1.0 kN. Her 75 kg boss dismisses Julie's worries and begins painting while standing 1.0 m from the end of the plank. If Julie's mass is 59 kg and the plank has a mass of 21 kg, then over what range of positions can Julie stand to join her boss without causing the ropes to break?

A 70 kg painter is painting the wall of a building. He stands on a horizontal board of length 4.5 m and mass 15 kg, suspended from vertical ropes attached to each end. If the painter stands 1.9 m from one end of the board, what would the tensions in the ropes be? tension in rope nearer to the painter tension in rope further from the painter

(17%) Problem 4: A painter (of mass 71 kg) needs to reach out from a scaffolding to paint the side of a building, so he lays a plank across two bars of the scaffolding, and puts a heavy bucket of mass 67 kg directly over one of the bars (see figure). You can assume the plank is massless, and is long enough to reach to the other building. L d ©theexpertta.com If the bars are separated by a distance 1.1...

A physics student of mass 59.0 kg is standing at the edge of the flat roof of a building, 12.0 m above the sidewalk. An unfriendly dog is running across the roof toward her. Next to her is a large wheel mounted on a horizontal axle at its center. The wheel, used to lift objects from the ground to the roof, has a light crank attached to it and a light rope wrapped around it; the free end of the...

STEP 1: In your own words define problem employees and the categories they may fall into. For the second or last paragraph provide your opinion on which employee type is the most difficult. DEFINITION : I think that "problem employees" are employees that either directly or indirectly hinder the organization's mission or vision, and break down into roughly four categories. In general, problem employees can be classified into two broad categories - employees creating problems for the organization and employees...
