An oscillating block of mass 250 g takes 0.15 sec to move between the endpoints of the motion, which are 40 cm apart. (a) What is the frequency of the motion? (b) What is the amplitude of the motion? (c) What is the force constant of the spring?

Quantity Value ------ Mass $m$ 250 g = 0.25 kg Time to move between endpoints 0.15 s Distance between endpoints 40 cm = 0.40 m Interpretation: Moving from one extreme endpoint to the other is half a full oscillation, so this time equals $T/2$. $$\frac{T}{2} = 0.15 \text{ s} \implies T = 0.30 \tex...
