A spring with a spring constant of 50 N/m is stretched by 0.5 m. What is the force exerted by the spring? A. 25 N B. 50 N C. 100 N D. 125 N 相关知识点: 试题来源: 解析 A。根据胡克定律 F = kx,其中 k 为弹簧常数,x 为伸长量。所以 F = 50 × 0.5 = 25 N。
A spring fo spring constant k is broken in the length ratio 1:3. The spring constant of larger part will be View Solution A spring of force constant800Nm−1has an extension of 5 cm. The work done in extending it from 5 cm to 15 cm is ...
1. A 20.0 cm long spring is attached to a wall. When pulled horizontally with a force of 100 N, the spring stretches to a length of 22.0 cm. What is the value of the spring constant? A spring with spring constant k=100 (N/m...
A mass of 0.20 kg , hung from a spring with a spring constant of 80.0 N/m , is set into an up-and-down simple harmonic motion. If the mass is displaced from equilibrium a distance and released at rest, its speed moving through the equilibrium position is 2.0 m/s. then what is t...
To solve the problem of finding the spring constant of each part when a spring of spring constant k is cut into three equal pieces, we can follow these steps: 1. Understand the Initial Condition: - We have a spring of length L and spring constant k. - The relationship between the sprin...
A spring with spring constant k=100 (N/m) is at its equilibrium length. a) How much elastic potential energy is stored in the spring? b) The same spring is stretched so that it is 6.0 cm longer than i What is the spring constant...
Question: A spring with a ‘spring constant’ of 600N/m is used in a scale for weighing fish.a) What is the mass of a fish that would stretch the spring by 7.5 cm from its normallength. b) whe extended as described, w...
Suppose a spring has mass m and spring constant k and let ω =√ (). Suppose that the damping constant is so small that the damping force is negligible. If an external force F(t)=F_0cosω_0 t is applied, where ω _0≠q ω , use the method of undetermined coefficients to show ...
在弹性系数(spring constant)k中,都有什么会影响弹簧的k值呢? 主要有三个因素: 材料、横截面积和原始长度, 其中原始长度越短,k值越大;横截面积越大,k值越大。K值是和整个弹簧的材料和形状都相关的。 在A-level数学的mechanics部分中,其实还有一个和弹性相关的物理量,叫做弹性模量(Elastic Modulus)λ。
