Physics Review Question

Unit: Mechanics
Year: 1996 Question#: 9
Question: 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. N

What is this question really asking?

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


























What's this question really asking?

What is the Force perpendicular? return to top
