Unformatted text preview: maini (nm7637) hw1 Shneidman (12108) 1 This print-out should have 12 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 Consider three force vectors vector F 1 , vector F 2 , and vector F 3 . The vector vector F 1 has magnitude F 1 = 57 N and direction 1 = 130 ; the vector vector F 2 has mag- nitude F 2 = 28 N and direction 2 = 140 ; and the vector vector F 3 has magnitude F 3 = 26 N and direction 3 = 120 . All the direction an- gles are measured from the positive x axis: counter-clockwise for > 0 and clockwise for < 0. What is the magnitude F of the net force vector vector F = vector F 1 + vector F 2 + vector F 3 ? Answer in units of N. 002 (part 2 of 2) 10.0 points What is the direction of the net force vector vector F ? State your answer as an angle between 180 and +180 . Answer in units of . 003 (part 1 of 2) 10.0 points Consider the two vectors vector M = ( a, b ) = a + b and vector N = ( c, d ) = c + d , where a = 4, b = 4, c = 3, and d = 3. a and c represent the x-displacement and b and d represent the y- displacement in a Cartesian...
