Compare the strain energy stored in the following: a) A tendon that is stretched 5 mm if the stiffness of the tendon is 10,000 N/m b) A diving board that is bent down 0.8 m if the effective spring constant is 833 N/m. 5m

A 5.0 kg weight is hanging from an ideal spring with a k of 250N/m.  It is pulled .15m from equalibrium.  Find it's maximum displacement the elastic potential energy of spring just as the block is being released the maximum speed the block will have during its motion the displacement of the block from equilibrium when the kinetic energy of the block is equal to the elastic potential energy of the spring The block is then brought to rest at equilibrium. The block is then pulled down half the original distance. Will the new period for the motion of the block be greater than, less than, or equal to the original period for the motion of the block?  Why?   The first block is brought to rest at equilibrium again.  An identical block is launched up into the first block. The new block is moving with an initial speed of v=5.0m/s when it collides with and sticks to the original block. Calculate the maximum compression of the spring after the collision of the two blocks.

The small 0.25-kg slider is known to move from position A to position B along the vertical-plane slot. Determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. The distance R = 0.83 m, the spring modulus k = 157 N/m, and the unstretched length of the spring is 0.61 m. B R 3 Answers: 0 k A (a) Work done on the body by its weight: Ug (b) Work done on the body by the spring: Us

A spring is stretched by 11.5cm. If the spring constant of the spring is 72.8N/m. How much elastic potential energy (in unit of joule) is stored in the spring?

1. A heavy crate (m = 23 kg) is resting on a frictionless inclined plane while suspended from a wall by a spring. The plane is inclined at an angle of 30° from the horizontal, and the spring is stretched from its equilibrium position by 25 cm. What is the spring constant of the spring? If the frictionless inclined plane is now replaced with an otherwise identical plane except with a rough surface, the crate now stretches the spring by 12 cm from its equilibrium position. What is the coefficient of static friction? You can assume that the static friction is at its maximum value. 30°

A bungee jumper stands on the top of a bridge, if her bungee cord is 24.0 m long and has a spring coefficient of 283 N/m and she has a mass of 48.3 kg. How tall must this bridge be for her bungee cord to stretch all the way to the ground? Number Units

3. When a 4.00-kg object is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.50 cm. If the 4.00-kg object is removed, (a) how far will the spring stretch if a 1.50-kg block is hung on it? (b) How much work must an external agent do to stretch the same spring 4.00 cm from its upstretched position?

One end of a spring is attached to a fixed wall while a 0.36-kg block is attached to the other movable end. The spring is stretched 0.6-m horizontally, then released from rest. Calculate its speed when it goes back to equilibrium if the spring's force constant is k = 5 N/m.
