Convert the following (x,y) Cartesian coordinates to (r, theta)
polar coordinates (record theta first in degrees and then radians):
a) (12,5) [m]
2. Convert the polar coordinates (13, 5.888) [m, rad] to
3. Find the angular momentum of a 2kg ball relative to the
origin if the ball is mivung 3 m/s, 20° north of east the instant
it is at (2, -3) [m] in relation to the origin. Sketch all of your
vectors and show your work.
4. This example involves a ball colliding with a bar that is
able to rotate. Is kinetic energy conserved in the elastic and
