9Question:
the diagram shows a person exerting a 300.-newton force on the handle of the shovel
that makes an angle of 60.° with the horizontal ground. The component of the 300.-newton force that acts perpendicular
to the ground is approximately(1
) 150. N(2
) 260. N(3
) 300. N(4
) 350. NWhat is this question really asking?
Explanation by: Dan M [ Return to question menu
]Answer 1
150. N INCORRECT This would be the answer you would get if the angle was 30° The answer doesn't fit formula sin = Opp/Hyp sin sin60° = x/300 return to top
Answer 2
260. N CORRECT Using the formula sin = Opp/Hyp sin sin60° = x/300 sin60 = x/300 x = 260. N return to top
Answer 3
300. N INCORRECT The answer doesn't fit formula sin = Opp/Hyp sin sin60° = x/300 return to top
Answer 4
350. N INCORRECT The answer doesn't fit formula sin = Opp/Hyp sin sin60° = x/300 return to top
