51Question:
As angle between the lawnmower handle and the horizontal increases, the horizontal component of F (1
) decreases(2
) increases(3
) stays the sameWhat is this question really asking?
Explanation by: Jay D (no last names) [ Return to question menu
]Answer 1
The horizontal component of F decreases CORRECT This is correct because as the handle(F) becomes more vertical, the angle increases and the horizontal force(Fh) decreases. (see diagram) return to top
Answer 2
The horizontal component of F increases INCORRECT This is incorrect because as the angle increases the horizontal force decreases. Consult the diagrams return to top
Answer 3
The horizontal component of F remains the same. INCORRECT This is incorrect consult the following diagrams. return to top
return to top
What's this question really asking?
This question is really asking, if you had an angle theta and there was a horizontal force involved what would happen to the the horizontal force if theta was increased. return to top |
