Unformatted text preview: Thevalingam, Donald Homework 9 Due: Dec 2 2006, midnight Inst: Eslami 1 This print-out should have 12 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. The due time is Central time. You want to master physics? Solve more problems. You want to solve problems but you cannot? Ask for help after you think about the problem. You do not want to learn physics? Tough luck! 001 (part 1 of 1) 10 points The magnitude of the vectors ~ F is 28 N, the force on the right is applied at an angle 55 and the the mass of the block is 24 kg. 24 kg F 5 5 F If the surface is frictionless, what is the magnitude of the resulting acceleration? An- swer in units of m / s 2 . 002 (part 1 of 1) 10 points A 626 kg block is pushed on the slope of a 35 frictionless inclined plane to give it an initial speed of 50 cm / s along the slope when the block is 1 . 2 m from the bottom of the incline. The acceleration of gravity is 9 . 8 m / s 2 . 6 2 6 k g 1 . 2 m 35 What is the speed of the block at the bot- tom of the plane? Answer in units of m / s....
