please answer parts e, f, and g
1. A2 kg mass attached to a spring with a spring constant of 400 N/m is pulled 10 cm from equilibrium
and then released at t = 0.
A) What is the angular frequency of the subsequent oscillation?
B) What is its frequency?
C) What is its period?
D) What is its amplitude?
E) What is its phase?
F) If it had been released at t=1 s, what would its phase be?
G) If it had been released at t 0 when the spring was compressed 10 cm, rather than stretched 10
cm, what would its phase be?
