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 ...

Physics
A 2.95 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0330 m. The spring has force constant 900 N/m. The coefficient of kinetic friction between the floor and the block is 0.42 . The block and spring are released from rest and ...

Physics
A block is suspended from the end of a spring. An external force holds the block so that initially the spring is not stretched or compressed. When the block is released, it oscillates up and down between positions A and B. If the mass of the block is 0.5 kg and the spring ...

Physics
How do you determine the force constant of a spring when given the mass of an object being hung vertically, and the distance the spring stretches? What formula and logic do I need?

Physics
Initially sliding with a speed of 2.1 m/s, a 2.1 kg block collides with a spring and compresses it 0.35 m before coming to rest. What is the force constant of the spring?

physics
A spring S of force constant k=100 N/m. is fixed to the base of a 30 degree incline.A mass m=50g. is held against the free end of the spring,so that the spring is compressed by 0.1 metre.If the mass is now released,calculate the distance travelled by the mass up the incline....
