sample1 = 20750 microseconds
sample2 = 20194 microseconds
MOI = 11.83 kg/m^2

rpm = (60000 / ((20750 / 1000) * 4)) == 722.89 rpm
rpm2 = (60000 / ((20194 / 1000) * 4)) == 742.7 rpm

rpm_gain = (742.7 - 722.89) == 19.81 rpm

gain_rads = (19.81/60) * (2*pi) == 2.074 rad/s

angular_velocity = (20750/60) * (2*pi) == 79.79 rad/s

angular_acceleration = (79.79 / 2.074) == 41.424 rad/s^2

torque = (11.83 * 41.424) == 429.667 newton metres

power = (429.667 * 722.89) / 9549) == 32.527 kilowatts
