Question

К вертикально подвешенной пружине жесткостью 400H/m прикрепили груз, так что пружина растянулась на 10 см. Чему равна масса груза?

Answer 1

Дано:
k=400H/m
Δx=10см=0.1м
Найти:
m-?
Решение:
F=mg
m=F/g
F=k*Δx=400*0.1=40H
m=40/10=4кг
Ответ: 4 кг

Answer 2

Calculating the Mass of the Load on a Vertically Suspended Spring

To calculate the mass of the load attached to a vertically suspended spring with a stiffness of 400 H/m, given that the spring is stretched by 10 cm, we can use the formula:

m = k * l where: - m = mass of the load - k = stiffness of the spring - l = elongation of the spring

Using the given values: - k = 400 H/m - l = 0.1 m (10 cm converted to meters)

We can calculate the mass of the load using the formula: m = k * l

m = 400 H/m * 0.1 m m = 40 kg

Therefore, the mass of the load attached to the vertically suspended spring is 40 kg.
