QUESTIONS The graphs below represents the motion of two objects for 60 second interval Object B traveis a constanteed of 12 ms. Object A change its motion after x seconda and B Velocily 18 60 3.1 Use the information in the graph to descnbe the entire motion of A in words. 3.2 What physical quantity does the area under the velocity - time graph represent? 3.3 Using the GRAPH ONLY (No equations of motion determine the: 3.3.1 Distance covered by object B lo 60 seconds. 3.3.2 Time, seconds, at which A must commence braking in order to travel the same distance as B does during the 60 seconds 3.4 Sketch the displacement-me graph for the motion of objects 15​

Matt is driving down 7th street. he drives 150 meters in 18 seconds. assuming he does not speed up or slow down, what is his speed?

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

Jasmine is diving off a 3-meter springboard. her height in meters above the water when she is x meters horizontally from the end of the board is approximated by the equation h=-x^2+3x+3. what is the maximum height jasmine will reach on her dive?
