A dog walking to the right with a speed of 1.5\,\dfrac{\text m}{\text s}1.5sm​1, point, 5, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction sees a cat and speeds up with a constant rightward acceleration of magnitude 12\,\dfrac{\text m}{\text s^2}12s2m​12, start fraction, start text, m, end text, divided by, start text, s, end text, squared, end fraction. What is the velocity of the dog after speeding up for 3.0\,\text m3.0m3, point, 0, start text, m, end text?

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

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.)

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
