Solution for QID #27142: 1) On a horizontal, frictionless surface, a block of mass m | StudyHelpMe

1) On a horizontal, frictionless surface, a block of mass m = 4 kg is attached to a spring of spring constant 200 N/m. The block is observed to undergo simple harmonic motion. Answer the following: (a) What is the period of the oscillation? (b) How would the period change if the mass were quadrupled, assuming the spring constant remains the same? 2) Light travels from air into a rectangular slab of unknown material. The angle of incidence is 25 degrees, and the angle of refraction is 15 degrees. (a) Find the index of refraction of the rectangular slab, and (b) what is the velocity of light in the slab?
