The length of a spring increases by 7.2 cm from its relaxed lengthwhen a mass of 1.4kg is hanging in equilibrium from the spring. (a)What is the spring constant? (b) How much elastic potential energyis stored in the spring? (c) A different mass is suspended and thespring length increases by 12.2 cm from its relaxed length to itsnew equilibrium position. What is the second mass?
answers in the back of the book say (a) 1.9N/cm (b) 0.49J (c) 2.4kg

A 750-gram mass is placed on a spring that lies on a frictionless surface. The spring has a spring constant k= 500 N/m and is at its equilibrium length.

(a). The spring is stretched so that it is 10 cm longer than its equilibrium length. how much elastic potential energy is stored in the spring?

(b). If the spring from part (a) is released. What is the speed of the mass as it passes through the equilibrium point (x=0)?

A certain coiled wire with uneven windings has the property that tostretch it an amount s from its relaxed length requires a forcethat is given by , so its behavior is different from a normalspring. You suspend this device vertically, and its unstretchedlength is 19.0 cm. You hang a mass of 17.0 grams from the device,and you observe that the length is now 21.0 cm. What is b? (Startyour analysis from the Momentum Principle.)

You hold the 17.0 gram mass and throw it downward, releasing itwhen the length of the spring-like device is 24.0 cm and the speedof the mass is 5.40 m/s. One millisecond later, what is theapproximate change in the speed of the mass?


At this same time, one millisecond after throwing, what is theapproximate change in the stretch of the device

Given a graph of Force vs. Position, where you have theforcefunction on the x-axis and the position function on they-axis, theinitial position is 0.0 and then it increases linearlyuntil itreaches 5.0meters where the force in (N) is about 12. Somyquestion is: This graph is for the force exerted by a spring asafunction of distance it is stretched from itsunstrechedlength.

a) What is the spring constant for this spring

b) What is the elastic PE if the spring is stretched 1.5 m fromitsequilibrium length

c) A Low friction cart of mass 5.0kg is attached to the spring,whenthe spring is stretched 1.5 m from its equilibrium length andthenthe cart is released what is the kinetic energy of the cartjust asthe spring passes through its equilibrium length? What isthevelocity of the cart at this position?
