READING QUIZ 1. In a polar coordinate system, the velocity vector can be written as v = v r u r + v θ u θ = r u r + r θ u . The term is called A) transverse velocity. B) radial velocity. C) angular velocity. D) angular acceleration. . . . 2. The speed of a particle in a cylindrical coordinate system is A) r B) r C) (r θ29 2 + ( r) 2 D) (r 2 + ( r) 2 + ( z) 2 . . . . . . .
The cylindrical coordinate system is used in cases where the particle moves along a 3-D curve. In the figure shown, the box slides down the helical ramp. How would you find the
