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?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
