g A thin uniform cylindrical turntable of radius 2.4 m and mass 32 kg rotates in a horizontal plane with an initial angular speed of 10 rad/s. The turntable bearing is frictionless. A clump of clay of mass 13 kg is dropped onto the turntable and sticks at a point 1.7 m from the point of rotation. Find the angular speed of the clay and turntable. Answer in units of rad/s.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
