An ultracentrifuge spins biological samples at very high speeds in order to separate their constituent microscopic components. one such instrument spins at 120,000 rpm, and the samples experience a centripetal acceleration of 6.6×10^6 m/s^2. what is the radius of the circle around which the samples travel?

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
