Chapt. 4 Two- and Three-Dimensional Kinematics Multiple-Choice Problems 004 qmult 00100 1 4 4 easy deducto-memory: kinematic quantities in multi-dimensions 1. “Let’s play Jeopardy ! For $100, the answer is: The vectors v r , vV = dv r dt , va = dvV dt = d 2 v r dt 2 .” What is most obvious quantities of , Alex? a) time b) light c) dynamics d) multi-dimensional kinematics e) rest 004 qmult 00110 1 1 3 easy memory: unit vectors in Cartesian coordinates 2. In Cartesian coordinates, kinematics is very simple if x ( t ), y ( t ), and z ( t ) are speci±ed because the unit vectors of Cartesian coordinates are: a) variables. b) dependent on time. c) constants. d) dependent on position. e) fewer than two. 004 qmult 00120 1 1 1 easy memory: unit vectors in polar/spherical coordinates 3. The unit vectors of polar and spherical polar coordinates are dependent on: a) the angular coordinates of the displacement vector. b) the magnitude of the displacement vector.
