Spring Force (Hooke's Law)

Scelta multipla
A spring with a spring constant of $100 \frac{N}{m}$ is attached to a rubber block with mass 3.0 kg. The block is resting on a concrete surface ( $μ_{s} = 1.0$ ). 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?

You push a 3-kg mass against a spring and release it from rest. Its maximum acceleration is 10m/s² when pushed back 0.5m. What is the (a) spring constant and the (b) restoring force at this point?

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?
