Calculate the ground state energy and corresponding speed of a particle of mass 1.0 g in a box of length L=10.0 cm assuming the particle in a box model. Compare these quantities with those of an electron in a box of length 1.0 nm. Can you measure the velocity of the particle using any measurement method that you can think of? Based on your results would you say the quantum mechanics breaks down when applied to ordinary objects?

An alien pilot of an intergalactic spaceship, on a mission to measure the sizes of galaxies, is traveling at 0.86c relative to the galaxy A. She determines the length of the short axis of the galaxy A to be 2.9 × 1017 km.
Suppose an initial speed of 21.4 m/s, at an angle of 61.10° with respect to the positive x axis. Find the velocity at time t0; enter x component, after that the y component.
A spring with spring constant 12.5 hangs from the ceiling. A 400 ball is attached to spring and allowed to come to rest. It is after that pulled down 6.80 and released. What is the time constant if the ball's amplitude has decreased to 3.90 after 57...
