m1 = 300 kg T1 = √2 s
m2 = 600 kg T2 = __ ?
T = 2π√(m/k)
T2 2π √(m2/k)
--- = -----------------
T1 2π √(m2/k)
T2
--- = √ (m2 / m1)
T1
T2 = √ (m2 / m1) · T1
T2 = √ (600 / 300) · √2
T2 = √2 · √2
T2 = 2 s ← jawaban
Ok ?
T1 = √2
m2 = 600 kg
ditanya : T2
T1 : T2 = 2π. : 2π.
√2 : T2 = : kedua ruas pangkatkan 2
2 : (T2)² = :
2 : (T2)² = 300 : 600
2 : (T2)² = 1 : 2
(T2)² = 2 . 2
(T2)² = 4
T2 = √4
T2 = 2 s
