Q. A 3.00 kg mass is attached to a vertical spring with a spring constant of 150 N/m . A student pushes on the mass vertically upward with her hand while slowly lowering it to its equilibrium position. Calculate the work done on the object by the gravitational force acting on it as it is lowered into position.

Q. When light with a wavelength of 206 nm is incident on a certain metal surface, electrons are ejected with a maximum kinetic energy of 2.57 x 10-19 J. Determine the wavelength (in nm) of light that should be used to double the maximum kinetic energy of the electrons ejected from this surface.
