Question

P10. A student has two springs with the spring constant k and two blocks with the mass m, but he has not read the lab manual, so he does not know how to assemble the experimental setup. (a) What would be the frequency of oscillations, if he connected one spring to the end of another, and then two blocks together to the end of this long spring? (b) What would be the frequency if the two springs are hanging parallel to each other, and one block is attached to both springs? (c) What is the frequency if the second block is attached to the first in (b)?

Explanation / Answer

a) k_equi=k/2 M=2m. so f=2pi*sqrt(k/4m). b).k_equi=2k. M=m so f=2pi*sqrt(2k/m). c). k_equi=2k M=2m so f=2pi*sqrt(k/m)
