A13-kg (including the mass of the wheels) bicycle has 1-m-diameter wheels, each with a mass of 3.1 kg. the mass of the rider is 38 kg. estimate the fraction of the total kinetic energy of the rider-bicycle system is associated with rotation of the wheels?

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Uppose we consider the system of the three capacitors as a single "equivalent" capacitor. given the charges of the three individual capacitors calculated in the previous part, find the total charge qtot for this equivalent capacitor. express your answer in terms of v and c.
