A hockey puck on ice is attached to a 0.50 meter radius pole with a 150 meter string. It
swings around the pole at a speed of 24.0 radis initially. After the string wraps around the pole
20 times, how fast will the puck be moving (in rad/s)? Use conservation of angular momentum
not energy (since work is done by the tension in the rope, kinetic energy changes so it's not
conserved).

The âdeath throesâ of stars are amongst the most complex phenomena in all of astronomy, and the âcorpsesâ of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a starâs life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
