How to find spring force, spring constant or distance stretched (Hooke's Law)

Spring Force

The Spring Constant of Hanging Springs

Calculus Work Required to Stretch a Spring - Hooke's Law

GCSE Physics - Elasticity, spring constant, and Hooke's Law  #44

 A spring with a spring constant of <math display=“inline”><mrow><mn>100</mn><mo rspace="thickmathspace">&#x2062;</mo><mrow><mfrac bevelled="true"><mi mathvariant="normal" class="MathML-Unit">N</mi><mi mathvariant="normal" class="MathML-Unit">m</mi></mfrac></mrow></mrow></math> is attached to a rubber block with mass 3.0 kg. The block is resting on a concrete surface (<math display=“inline”><mrow><msub><mi>&#x03BC;</mi><mi mathvariant="normal" class="MathML-Unit">s</mi></msub><mo>=</mo><mn>1.0</mn></mrow></math>). The spring is pulled to the side until the block begins to slip. What is the maximum extension of the spring before the block slips? 

<p>You push a 3-kg mass against a spring and release it from rest. Its maximum acceleration is 10m/s&lt;sup2&gt;&lt;/sup&gt; when pushed back 0.5m. What is the (a)spring constant and (b) restoring force at this point?</p>

Acceleration of Mass-Spring Systems

Simple Harmonic Motion: Hooke's Law

<p>A 1.0 m-long spring is laid horizontally with one of its ends fixed. When you pull on it with 50 N, it stretches to 1.2 m. (a) What is the spring’s force constant (b) How much force is needed to compress it to 0.7 m?</p>

 A 1.1 m length of string has a radius of 1.2 mm. It stretches by 1.2 cm when a 5.6 kg mass is suspended from it. What is Young’s modulus of the rope? 

Hooke's Law Introduction - Force of a Spring

 A 20.0 cm massless spring with spring constant 340 N/m is suspended from the ceiling. A student carefully hangs a 450 g mass from the free end. How long is the spring now?
