Ross (jr6585) – HW09 – Ross – (08152) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points A force vector F = F x ˆ ı + F y ˆ acts on a particle that undergoes a displacement of vectors = s x ˆ ı + s y ˆ . Let: F x = 8 N, F y = - 5 N, s x = 3 m, and s y = 3 m. Find the work done by the force on the particle. Answer in units of J. 002 (part 2 of 2) 10.0 points Find the angle between vector F and vectors . Answer in units of . 003 10.0 points A man lifts a 16 . 9 kg bucket from a well and does 3 . 37 kJ of work. The acceleration of gravity is 9 . 8 m / s 2 . How deep is the well? Assume that the speed of the bucket remains constant as it is lifted. Answer in units of m. 004 (part 1 of 4) 10.0 points A 50 . 7 kg box initially at rest is pushed 2 . 19 m along a rough, horizontal floor with a constant applied horizontal force of 163 . 367 N. If the coefficient of friction between box and floor is 0 . 297, find the work done by the applied force.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
