38.- A 50 kg woman is standing on the edge of a large 110 kg disk with a radius of 4.0 m that rotates at 0.50 (rev / s) about an axis that passes through the center of her. Calculate the magnitude of the total angular momentum of the woman-disc system (assume that the woman can be treated as a point). 28.- Express the kinetic energy of an electron moving at a speed of 106 m/s in eV. Repeat it for a proton. 18.- A stone is dropped from a height of 100 m. How long does it take to fall a) the first 50 m? b) the seconds 50 m?
