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 + F y acts on a particle that undergoes a displacement of vectors = s x + s y . Let: F x = 9 N, F y =- 5 N, s x = 6 m, and s y = 2 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 shopper in a supermarket pushes a cart with a force of 35 . 6 N directed at an angle of 23 . 4 downward from the horizontal. Find the work done by the shopper as she moves down a 51 . 6 m length of aisle. Answer in units of kJ. 004 10.0 points Hint: W = vector S vector F . Consider a force vector F with components F x = 31 N, F y = 40 N, and F z = 73 N, as illustrated in the figure below.in the figure below....
