A 0.57-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.12 m to 0.23 m (relative to its unstrained length), the speed of the sphere decreases from 6.4 to 4.0 m/s. What is the spring constant of the spring? Number Units
loss in KE = = gain in spring energy
=> 1/2*K*(0.23^2 - 0.12^2) = 1/2*0.57*(6.4^2 - 4^2)
=> K = 369.53 N/m

A 0.53-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.12 m to 0.23 m (relative to its unstrained length), the speed of the sphere decreases from 6.6 to 4.4 m/s. What is the spring constant of the spring?
A 0.43-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.12 m to 0.23 m (relative to its unstrained length), the speed of the sphere decreases from 7.2 to 4.8 m/s. What is the spring constant of the spring?
A 0.48-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.12 m to 0.23 m (relative to its unstrained length), the speed of the sphere decreases from 7.5 to 4.2 m/s. What is the spring constant of the spring? *** this is the 3rd time I post this question. Previews answers were: 454.2 and 1074.6 and NONE of them were right. Please just answer if you are sure of what you doing. Thank...
Chapter 10, Problem 38 GO Your answer is partially correct. Try again. A 0.49-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.12 m to O.23 m (relative to its unstrained length), the speed of the sphere decreases from 6.9 to 3.3 m/s. What is the spring constant of the sp ring? Unit

A 0.57-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstrained length increases by a factor of 5. What is the mass of the second block?
A 1.1-kg object is suspended from a vertical spring whose spring constant is 180 N/m. (a) Find the amount by which the spring is stretched from its unstrained length. (b) The object is then pulled straight down by an additional distance of 0.12 m and released from rest. Find the speed with which the object passes through its original position on the way up.

A 9.10 kg object oscillates at the end of a vertical spring that has a spring constant of 2.25 times 10^4 N/m. The effect of air resistance is represented by the damping coefficient b = 3.00 N s/m. Calculate the frequency of the dampened oscillation. By what percentage does the amplitude of the oscillation decrease in each cycle? Find the time interval that elapses while the energy of the system drops to 3.00% of its initial value.
