Unformatted text preview: Thevalingam, Donald – Homework 8 – Due: Nov 13 2006, midnight – Inst: Eslami 1 This print-out should have 17 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 For the ballistic missile aimed to achieve the maximum range of 17500 km, what is the maximum altitude reached in the trajectory? Answer in units of km. 002 (part 1 of 3) 10 points An object has a mass of 39 kg. The acceleration of gravity is 9 . 8 m / s 2 . What is its weight on the earth? Answer in units of N. 003 (part 2 of 3) 10 points What is its mass on the moon where the force of gravity is 1 6 that of the earth? Answer in units of kg. 004 (part 3 of 3) 10 points What is the weight of that object on the moon? Answer in units of N. 005 (part 1 of 1) 10 points A ball of mass M is suspended by a thin string (of negligible mass). An upward force F pulls on the string as shown in the figure below. The relation between the tension in the string T and the weight of the ball M g is given in each statement below. M T F While T < M g , the ball’s acceleration must be constant, with its velocity either up- wards, downwards, or zero....
