The car's motion can be divided into three different stages: its motion before the driver realizes he's late, its motion after the driver hits the gas (but before he sees the police car), and its motion after the driver sees the police car. which of the following simplifying assumptions is it reasonable to make in this problem? during each of the three different stages of its motion, the car is moving with constant acceleration. during each of the three different stages of its motion, the car is moving with constant velocity. the highway is straight (i. e., there are no curves). the highway is level (i. e., there are no hills or valleys).

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
