Now assume that the pitcher in part d throws a 0.145-kg baseball parallel to the ground with a speed of 32 m/s in the +x direction. the batter then hits the ball so it goes directly back to the pitcher along the same straight line. what is the ball's x-component of velocity just after leaving the bat if the bat applies an impulse of −8.4n⋅s to the baseball?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

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.
