Q1. A 240 g block hangs from a spring with spring constant 8.0cm. At the block is 23cm below the equilibrium point and moving upward with a speed of 119cm/s. What are blocks-

what is block's distance from equilibrium is when the speed is 69 cm /s?

What is block's position at t=10s?

Q2. A monochromatic beam of light is absorbed by a collection of ground-state hydrogen atoms in such a way that three different wave-lengths are observed while the hydrogen relaxes back to the ground state.

What is the wavelength of the incident beam?

Response in units of nm.
