Respuesta :

m= 2.4 kg

Amplitude = maximum displacement = 3 cm

period = time to complet 1 cycle = T = 0.8 s

frequency = 1/T = 1 /0.8 = 1.25 hz

angular frequency = ω= 2 pi f = 2 pi x 1.25 = 7.85 rad/s

Constant of the spring:k

ω = √k/m

k = ω^2 m = (7.85)^2 * 2.4 = 147.894 N/m

Answers:

A) Period = 0.8 s

B) Frequency = 1.25 hz

C) Angular Frequency= 7.85 rad/s

D) Amplitude =3cm

E) Spring Constant = 147.894 N/m
