19.8. consider the simple harmonic oscillation where the force constant is 19.6n/m.
x = -(0.100m) cos8.081, and v = (0.808 m/s) sin 8.081, determine: (a) the total energy, (b) the kinetic and
potential energies as a function of time, (c) the velocity when the mass is 0.050 m from equilibrium.
(d) the kinetic and potential energies at half amplitude (x = = a/2).

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
