If a single constant force acts on an object that moves on a straight line, the object's velocity is a linear function of time. the equation v = v_i + at gives its velocity v as a function of time, where a is its constant acceleration. what if velocity is instead a linear function of position? assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = v_i - kx, where k is a constant coefficient and x is the position of the object. find the law describing the total force acting on this object. (enter an expression for the magnitude of the total force. use the following as necessary: m, k, and v.)

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
