Unformatted text preview: Exam Next Tuesday, 70-2690, 6:00pm Exam will have 2 parts: 50% common multiple choice ( 10 problems), 50% problems (2ish). w/formula sheet. Topics: units, conversions, and significant figures vectors (graphical addition, numerical addition, resolving magnitudes, etc...) uncertainties (statistical & graphical) simple kinematics (position diagrams, etc...) moderate 1-d kinematics problems (1 object, kinematics equations) Units and Conversions The position in meters of an object is given by x = a p ( t ) . What are the units of a ? a) m b) m/s c) m s d) m/ t e) m t Approximately how many cubic inches are there in 1 m 3 ? (2.54 cm = 1 in) a) 39 b) 1600 c) 61,000 d) 4 How many significant figures are there in 0.0020? a) 1 b) 2 c) 3 d) 4 e) 5 Vectors Draw a vector ~a and ~ b . Draw the resultant vector ~a + ~ b and ~a- ~ b . Given vectors ~a = 3 x- 2 y + 4 z and ~ b =- 4 x + 2 y + 4 z , what is ~a + ~ b ? ~a- ~ b ? What is the angle between ~a and ~ b ? What angle does ~a make with the x- axis? Uncertainties...
