A spring has an unstretched length of 10 cm . It exerts a restoring force F when stretched to a length of 12 cm . For what total stretched length of the spring is its restoring force 3F? At what compressed length is the restoring force 2F? I keep doing this but I do not think ...

A 2.1 kg block slides with a speed of 1.1 m/s on a frictionless, horizontal surface until it encounters a spring. (a) If the block compresses the spring 5.7 cm before coming to rest, what is the force constant of the spring? (b) What initial speed should the block have to ...

Hooke's law states that the distance an object is stretched varied directly with the force exerted on the object. Suppose the force exerted by 7-kg mass stretches a certain spring 5 cm. To the nearest 0.1 cm. how far will the spring be stretched by the force of an 11-kg mass? ...

An 8 g bullet is shot into a 4.0 kg block, at rest on a frictionless horizontal surface. The bullet remains lodged in the block. The block moves into a spring and compresses it by 7.9 cm. The force constant of the spring is 1400 N/m. What is the impulse of the block (including...

Physics
Hooke's law states that it takes a force equal to kΔx is required to stretch a sorting a distance Δx beyond its rest length. A) determine a formula in terms of k & Δx that represents the amount of work required to stretch a spring to a distance Δx. Hint: ...

A 250g wood block firmly attached to a horizontal spring slides along a table with a coefficient of friction of 0.40. A force of 30.N compresses the spring 20cm. If the spring is released from this position what will be the block's speed when it passes equilibrium position?

A 3.0 kg brick rests on a perfectly smooth ramp inclined at 34 above the horizontal. The brick is kept from sliding down the plane by an ideal spring that is aligned with the surface and attached to a wall above the brick. The spring has a spring constant (force constant) of ...
