Jasmine sat on a playground toy attached to a spring. When she sat down, the height of the toy reduced from 1.2 m to 0.95 m. Jasmine has a mass of 45 kg. What is the spring constant of the playground toy?

A vertical spring 0.100 meter long is stretched to a length of 1.25 meters when a 2 kilogram mass is attached to the bottom. What is the correct value for the spring constant of this spring?

Hooke's law describes a certain light spring of unstretched length 33.0 cm. When one end is attached to the top of a door frame and a 5.00-kg object is hung from the other end, the length of the spring is 48.5 cm. Answer parts a-b.

The tension in a ligament in the human knee is approximately proportional to the extension of the ligament, if the extension is not too large. If a particular ligament has an effective spring constant of 152 N/mm as it is stretched, what is the tension in this ligament when it is stretched by 0.800 cm?

A spring with a spring constant of 51.1 N/m is hung from the ceiling. A block is then attached to the free end of the spring. When released from rest, the block drops 0.160 m before momentarily coming to rest, after which it moves back upward. What is the mass of the block?

A block of mass, 1.5 kg is attached and secured to an end of a spring with a spring constant of 10,000 N/cm. The other end of the spring is secured to the wall. The block is pushed against the spring, which compresses the spring to a position of x = -0.04 cm. When uncompressed, the end of the spring that is attached to the block is at a position of x = 0.00 cm. The block/spring system is then released from rest, and the block travels along a rough horizontal track for the length of the spring. At 0.00 cm the surface changes. Can you help me calculate the block's velocity once it leaves the spring? Thank you.
