An unstretched spring is 11.0 cm long. When you hang an 590 g weight from it, it stretches to a length of 14.0 cm. what is the force constant in (N/m) of this spring? what is the total mass must you hang from the spring to stretch it to a total length of 18cm?

Physics
A light spring having a force constat of 125 N/m is used to pull a 9.50kg sled on a horizontal frixtionless ice rink. If the sled has an acceleration of 2.00 m/s^2, by how much does the spring stretch if it pulls on the sled (a) horizontally, (b) at 30.0 degrees above the ...

Physics
A 0.30 kg mass is attached to a spring with a spring constant 170 N/m so that the mass is allowed to move on a horizontal frictionless surface. The mass is released from rest when the spring is compressed 0.15 m. (a) Find the force on the mass. N (b) Find its acceleration at ...
