An obnoxious brat assigns his 18.7-gram pet mouse Mickey the role of stunt mouse by stuffing him into a spring gun and shooting him up into the air at some angle. The gun\'s spring has a force constant of 90.1 N/m and is initially compressed 12.7 cm. When Mickey reaches maximum height, he has a horizontal velocity with a speed of 2.43 m/s. How high above his initial location in the gun does Mickey soar? (In case you are worried, a miniature parachute opens at this point and Mickey lands safely. The brat is slightly less obnoxious than we thought.) Take g = 9.81 m/s2.
An eagle is flying horizontally at 7.8 m/s with a fish in its claws. It accidentally drops the fish, How much time passes before the fish's speed doubles
Two nanowires are separated by 1.6 nm as measured by STM. Inside the wires the potential energy is zero, but between the wires the potential energy is greater than the electron's energy by only 1.4 eV.

A 0.180-kg yo-yo consists of two solid disks of radius 12.00cm joined together by a massless rod of radius 1.00 cm, Find the acceleration of the yo-yo
A photon of wavelength 0.1800 nm strikes a free electron that is initially at rest, What is the energy of the photon (in eV) after it has scattered from the electron
A constant current of I = 15 A exists in a solenoid whose inductance is L = 42.2 H. The current is then reduced to zero in a certain amount of time. If the current goes from 15 to 0 A in a time of 75 ms, what is the emf induced in the solenoid
