PHY 121 Spring 2020 Exam 3 3) A 15.0 kg stone slides down a hill, leaving point A at a speed of 12.0 m/s. There is friction on the hill between points A and B, but there is no friction on the level ground at the bottom of the hill, between B and the wall. The energy lost due to friction in the hill section between points A and B is 1000 J. After entering the smooth horizontal region, the stone travels 100 m and then runs into a very long, light spring with force constant 5000 N/m

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.

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.)
