Hello.
Some eartquakes are more daminging becasue of the high frequency. Some earthquakes have higher then others. And the location places with less people have smaller earthqakes then places with a lot. The earthquake in i<span>ndian Ocean</span> hurt over a miilon people but the one in Hati only left things in poor condation.
Have a nice day
When they meet the 40-kg boy would have moved a distance of 6 m.
<h3>Distance moved by the 40 kg boy</h3>
Apply the principle of center mass;
Take the 40 kg mass as the reference point;
X(40 kg) = (40kg x 0 + 60kg x 10 m)/(40 kg + 60 kg)
X(40 kg) = (600)/(100)
X(40 kg) = 6 m
Thus, when they meet the 40-kg boy would have moved a distance of 6 m.

it's true because we'll engery and causes of matter work together I think
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>
