Excatly what do you need help with hunny
Sound is a form of energy, just like electricity and light. A sound is made when air molecules vibrate and move in a pattern called waves, or sound waves.
<span>We can use a simple kinematic equation to find the velocity of the ball.
v = v0 + at
v = 58.5 m/s + (-9.80 m/s^2) (5.97 s)
v = -0.006 m/s
The negative sign means that the ball is heading down toward the ground. The small magnitude of the velocity means that the ball has reached the maximum height and is starting to fall back down toward the ground.
The velocity of the ball is -0.006 m/s</span>
