you go rock climbing with a pack that weighs 70 Newton’s, and you reach a height of 30 m. How much work did you do to lift your pack? If you finished the climb in 10 minutes (600 s), what was your power

x ≈ 8.57

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

7(15 + x) = 165 ← distribute left side

105 + 7x = 165 ( subtract 105 from both sides )

7x = 60 ( divide both sides by 7 )

x ≈ 8.57 ( to 2 dec. places )
