question 278

Multiple Choice

Solve the problem.
-Determine the resultant effect of three people pulling on a car as shown in the drawing.


$\mathrm { a } = 90.0 \mathrm { lb } , \mathrm { b } = 47.0 \mathrm { lb } , \mathrm { c } = 124.0 \mathrm { lb } , \mathrm { d } = 42 ^ { \circ } , \mathrm { e } = 41 ^ { \circ }$
Round results to an appropriate number of significant digits.

• A) \(| \mathrm { F } | = 29 \mathrm { lb } , \theta = - 46 ^ { \circ }\)
• B) \(| \mathrm { F } | = 251 \mathrm { lb } , \theta = 34 ^ { \circ }\)
• C) \(| \mathrm { F } | = 143 \mathrm { lb } , \theta = 82 ^ { \circ }\)
• D) \(| F | = 209 \mathrm { lb } , \theta = - 6 ^ { \circ }\)
