Auniform, solid sphere of radius and mass starts with a purely translational speed of at the top of an inclined plane. the surface of the incline is long, and is tilted at an angle of with respect to the horizontal. assuming the sphere rolls without slipping down the incline, calculate the sphere's final translational speed at the bottom of the ramp.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
