Abox is held at rest by two ropes that form 30° angles with the vertical. the tension t in either rope is 42 n. what is the weight (w) of the box?

36 n

79 n

86 n

73 n

62 n

= 73 N

Using the formula

2 T cos(30°) = w

Where; T is the tension on each string, while w is the weight of the box given by mg

Therefore;

W = 2Tcos 30°

    = 2 × 42 cos 30°

    = 84 cos 30°

    = 72.74

  ≈ 73 N

568.98

false

explanation:

boats, things on boats luggage are way more heavy then water.
