A spring-mass system has a natural period of $0.21 \mathrm{~s}$. What will be the new period if the spring constant is (a) increased by $50 \%$ and (b) decreased by $50 \% ?$
$\bullet\bullet$ (a) If the spring constant in a mass-spring system is halved, the new period is $(1) 2,(2) \sqrt{2},(3) 1 / \sqrt{2},$ (4) $1 / 2$ times the old period. Why? (b) If the initial period is $2.0 \mathrm{~s}$ and the spring constant is reduced to $1 / 3$ of its initial value, what is the new period?
A block attached to a spring with unknown spring constant oscillates with a period of $2.0 \mathrm{s}$. What is the period if a. The mass is doubled? b. The mass is halved? c. The amplitude is doubled? d. The spring constant is doubled? Parts a to d are independent questions, each referring to the initial situation.
