Vectors are quantities for which the direction matters as much as the size. For example, when investigating the forces acting on a person in an elevator, it makes sense to tell the directions of the forces as well. As such...
Consider the following figure: B→−2A→ Vectors: a→ |a| α a→=(|a|cosα,|a|sinα) Answer and Explanation:1 The components of the vectorvecAare given by: {eq}\displaystyle \vec{A} = \Big(|A|\cos(28^{\circ}), |A|\sin(28^{\circ})\...
Consider the vectors \vec{A} and \vec{B} shown below. Which of the other four vectors (\vec{C}, \vec{D}, \vec{E}, \vec{F}) in the figure best represent the direction of: a. \vec{A} + \vec{B}, b...
Choose one of the following four choices. A. at point A or at point B B. at point B Consider the beam shown in the figure. Suppose that d = 3.4 m . a) Determine the equivalent resultant force. b) Determine the ...
