Three ropes pull on a knot shown in (Figure 1) . The knot is not accelerating. A partially completed force diagram for the knot is shown in the figure (Figure 2) . Use Newton's second law to determine the magnitudes of the forces that ropes 2 and 3 exert on the knot. Suppose that T1onK = 1000 N .

1. Determine the magnitude of the force that rope 2 exerts on the knot. Express your answer to two significant figures and include the appropriate units.

2. Determine the magnitude of the force that rope 3 exerts on the knot. Express your answer to two significant figures and include the appropriate units.
