Question

На сколько удлинится рыболовная леска жестокостью 0,5 кН/м при равномерном поднятии вертикально вверх рыбы массой 200г?

Answer 1

Mg:k(дробью)=4*10(-3степень)м=4мм
P.S-не знаю поймешь ли ты...

Answer 2

Calculating the Extension of Fishing Line

To calculate the extension of the fishing line when lifting a fish vertically, we can use the formula:

Extension (Δl) = Force (F) / (k * g)

Where: - Δl = Extension of the fishing line - F = Force applied (weight of the fish) - k = Spring constant (in this case, the stiffness of the fishing line) - g = Acceleration due to gravity (approximately 9.81 m/s^2)

Given: - Force (F) = 0.2 kg * 9.81 m/s^2 (mass of the fish * acceleration due to gravity) - Stiffness (k) = 0.5 kN/m (stiffness of the fishing line)

Calculation

Using the given values: - F = 0.2 kg * 9.81 m/s^2 = 1.962 N - k = 0.5 kN/m = 500 N/m

Plugging these values into the formula: Δl = 1.962 N / (500 N/m * 9.81 m/s^2)

Result

After calculating, the extension of the fishing line due to the force of lifting a fish with a mass of 200g vertically would be approximately 0.004 meters.

This calculation is based on the provided formula and the given values for force and stiffness of the fishing line
