A 0.5 kg block hangs on a spring and oscillates vertically with amplitude 2 cm and period 0.5 s. The spring is never compressed. Find the minimum force the spring exerts on the block, in N ( $g = 9.8$ m/s²).

Answer:

3.32

Solution:

$F_{min} = m g - m ω^{2} A$ . With $ω = 4 π$ rad/s, $m ω^{2} A = 1.58$ N, so $F_{min} = 3.32$ N.
