Two pulley wheels of radii 0.2 m and 0.59 m are mounted rigidly on a common axle and clamped together. The combined moment of inertia of the two wheels is 3.4 kg⋅m^2.
A mass 130 kg is attached to a cord wrapped around the smaller wheel and another mass of 69 kg is attached to another cord wrapped around the larger wheel.
Find the angular acceleration of the system. Take clockwise direction as positive. The acceleration of gravity is 9.8 m/s^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?
