It takes 6.5 J of work to stretch a spring 4.1 cm from its unstressed (relaxed) length. a) How much (in J) spring potential energy is then stored by the spring? b) What is the spring constant k in N/m? c) What if the spring is compressed instead by 4.1 cm from its unstressed length, how much (in J) spring potential energy is then stored by the spring? d) How much work (in J) is needed to compress the spring...
If it requires 9.2 J of work to compress a spring by 4 cm from equilibrium, how much work would it require to stretch the spring by 6 cm from equilibrium?
It takes 23 N of force to compress a very light spring 19 cm. The spring is placed parallel to a table and its ends are firmly attached to the wall and to a 180-g wood block (Figure 1). The coefficient of kinetic friction between the block and the table is 0.34. The spring is compressed a second time to 19 cm and then released from rest. Part A How far beyond its equilibrium position will it stretch on its...
How much work must be done to A) compress a spring 4.0 cm if the spring constant is 55 N/m? B) stretch a spring 8.0 cm if the spring constant is 85 N/m?
If 14 J of work are needed to stretch a spring 20 cm beyond equilibrium, how much work is required to compress it 6 cm beyond equilibrium? If 14 J of work are needed to stretch a spring 20 cm beyond equilibrium, how much work is required to compress it 6 cm beyond equilibrium? (Use decimal notation. Give your answer to three decimal places.) W-

Question 15 A spring required a force of 5.0 N to compress it 0.1 m. How much work is required to stretch the spring 0.4 m? Hint: Work done is equal to the change in elastic potential energy 0.8) O 0.4) 2) 0.2
A spring is compressed 3.0 cm. Part A How far must you compress a spring with twice the spring constant to store the same amount of energy? Express your answer with the appropriate units. Δx=
A force of 4.9 N is required to stretch a certain spring by 1.3 cm. Part A: How far must this spring be stretched for its potential energy to be 0.025 J? Part B: How much stretch is required for the spring potential energy to be 0.075 J?
