Explanation / Answer

An oscillator consists of a block of mass 0.550 kg connected to a spring. When set into oscillation with amplitude 40.0 cm, it is observed to repeat its motion every 0.900 s.

Find the spring constant.

Find the maximum speed.

Find the maximum force exerted on the block

ans :

T = 0.9 = 2 ( m / k )

0.9 = 2 ( 0.55/ k )

k = 0.268 N /m , spring onstnat ans

v = srt ( k / m ) * 0.4 = 0.2792 m /s velocity

F = kA = 0.268 * 0.4 = 0.1072 N ans , force
