Unformatted text preview: the vertical axis. At time t = 0 the puck is released at height h with a purely angular initial velocity ω0 . Figure 1: (a) Write down Newton’s second law first in terms of cartesian coordinates and then in terms of cylindrical polar coordinates. Which form would be easiest to use to solve for the motion of the ball described above? Why? (If you need a reminder about what cylindrical polar coordinates are, problem 1.47 on p. 40 of Taylor might help. If you need a reminder about Newton’s law in other coordinate systems, you might look back to Taylor’s discussion that led up to Eq 1.48 ) (b) Describe and/or sketch a prediction of what the motion of the ball will be for t > 0 . You can assume that h and ω are positive, and that the ball is subject to the force of gravity (on earth) which points in the −z direction. ˆ (c) Use the equations you wrote in part...
