Problem B12: George is swinging on a playground swing. The length of the swing is l, and George's weight is W. At the bottom of the swing, George's speed is v=n1 meters/sec. The value of l times g is equal to lg = n2 (meters/sec)2. If the swing is held up by two ropes, what is the tension T in each rope. That is, if T = n3 W/2, what is n3? Note, that if the speed were zero, the tension in each rope would be W/2.

n1=2, n1=1

Explanation / Answer

4.56N [13 degrees above the horizontal] 4.56N because the two ropes are tied and force tension on each rope is 2.28N...unless ur saying the total tension in the whole rope is 2.28...then it wud be 2.28N[13 degrees above horizontal]
