A 41.0-kg child swings in a swing supported by two chains, each 3.04 m long. The tension in each chain at the lowest point is 348 N.
A child's swing is held up by two massless ropes tied to a tree branch. The distance between the ropes at the top of the swing is less than the distance between the ropes at the bottom, so that the ropes hang 14.01° from the vertical (see the picture). If the tension in each rope is 2.4 N, what is the weight of the swing?

QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.
