A block weighing w newtons is suspended from a horizontal support by two wires. The first wire extends up and to the left from the block, making a 41 degree angle with the horizontal support. A vector extending from the block along the first wire is labeled F 1. The second wire extends up and to the right from the block, making a 31 degree angle with the horizontal support. A vector extending from the block along the second wire is labeled F 2

What is the​ weight, w?

What is the magnitude of F1?

The diagram below shows a block of mass m=2.00kgm=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00NF1=4.00N, F2=6.00NF2=6.00N, and F3=8.00NF3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...

Engineering students are learning to use phasor diagrams to analyze RLC series circuits. They are given the following phasor diagram, and they are told that the AC power source has a frequency of 60.0 Hz and the resistor has a resistance of 84.0 Ω. Four vectors and a directional arrow are positioned on a coordinate plane. All vectors begin at the origin. In counterclockwise order, starting from the bottom: a vector labeled ΔVC = 15.0 V points down along the...
