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....
