That is an Elastic collision
Answer:
D = 26.97 m
Explanation:
given,
you walk 12.5 m in a direction exactly 19° south of west
after that 19.5 m in a direction exactly 39° west of north.
distance calculation from the starting point = ?
D₁ = d₁ cos θ
D₁ = 12.5 x cos 19°
D₁ = 11.82 m
D₂ = d₂ cos θ
D₂ = 19.5 x cos 39°
D₂ = 15.15 m
distance from the starting point
D = D₁ + D₂
D = 11.82 + 15.15
D = 26.97 m
Distance from the starting point is equal to 26.97 m
That makes no sense I can't help sorry
