Displacement. velocity is the rate of change of the displacement
Volume is<span> proportional to the </span>amplitude<span> of the sound wave</span>
Answer:
Calculate the potential energy, kinetic energy, mechanical energy, velocity, and height ... LA 59 kg man has a total mechanical energy of 150,023 J. If he is swinging ... ME=2881.2 J b. What is Julie's speed just as she hits the water? v=J 2.KE.
Explanation:
Final angular velocity = initial angular velocity plus the product of angular acceleration and time
<span>w = wo + at </span>
<span>( 1/2 ) wo = wo + at </span>
<span>- ( 1/2 ) wo = at </span>
<span>- ( 1/2 ) ( 88 rad / s ) = a ( 4.40 s ) </span>
<span>a = -10 rad /s </span>
<span>Newton's Second Law, rotational form: Torque (force perpendicular to radius) is equal to the product of moment of inertia and angluar acceleration </span>
<span>Fr = I a </span>
<span>F ( .0700 m ) = ( .850 kg m^2 ) ( -10 rad / s ) </span>
<span>F = 120 N</span>
