Asupernova results when a star that has used up all of its fuel undergoes an extremely violent explosion and its mass is blown outward. consider the star, before the explosion, to be a solid sphere of radius r rotating with an angular speed of 2.0 rev/day. once the star explodes its mass rapidly expands into a spherical shell. assuming that all of the star's mass is contained within this spherical shell and there are no external torques acting on it, what is the angular speed of this mass when the radius of the spherical shell is 5.8r?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
