**99 points** i will give brainliest answer! explain answer! a squirrel sees a big acorn being thrown from a tree by a chipmunk and attempts to snatch it. the acorn is thrown from a 10.0 m high branch and with a horizontal velocity of 1.1 m/s. the squirrel on the ground is 5.0 m from the base of the tree. what is the of the squirrel’s average velocity if it grabs the acorn in its mouth just as it touches the ground?

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele
