the three ropes in the figure are tied to a small, very light ring. two of the ropes are anchored to the walls at right angles, and the third rope pulls as shown. what are t1 and t2, the magnitudes of the tension forces in the first two ropes?

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
