The spring below has a spring constant of 50. N/m. A 1 kg block is pulled horizontally to the right and held motionless on a frictionless surface. The spring is stretched 0.30 m. Show all of your work. -am m 6. Recall the equation for the conservation of energy (E,-E). Write an equation for the conservation of energy in the bungee cord in terms of PE, PEspring, and KE. Do not plug in numbers yet. 7. Using the equation from question 6, substitute in m, g, h, v, k, and x and write this new equation below. 8. What force does the spring exert on the block when the spring is stretched by 0.30 m? 9. The block is released. a. What is the initial speed of the block? b. What is the initial and final height of the block? c. What maximum speed will the block obtain? The spring below has a spring constant of 50. N/m.

Answer rating: 100% (QA)

To find the force exerted by the spring on the block we use Hookes law F k x where F is force k is spring constant and x is displacement of the spring from its equilibrium position The negative sign i... View the full answer
