A scooter rider begins at 4.0 m/s, then is accelerated with a constant acceleration of 5.0 m/s2 for 5.0 s. Next, the rider hit the brakes and slows down to a stop with a deceleration of 6.0 m/s2. How far did the scooter travel in the complete motion?

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.)
