You are walking in the forest with some friends when a wild bear shows up! naturally, you all begin running faster. assume that you had an initial velocity of 0.5 m/s. after running for 20 seconds, you are 50 meters away from where you started. if you accelerated at a constant rate, what must your final velocity be?

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
