An object of mass m = 0.25kg has a horizontal spring attached to its left side, and
slides along a frictionless surface. The spring constant is ? = 0.4 N . At t = 0s, the m
object is displaced 0.1m to the right of its equilibrium position. Its initial velocity is 0.4 m , toward the right.
a) What is the period T of the motion?
b) What is the angular frequency ? ?
c) What is the frequency ? ?
d) What is the total energy E ?
e) What is the amplitude A of the motion? (careful!)
f) What is the phase angle ? ?
g) What is the maximum velocity vmax? (careful!)
h) What is the maximum acceleration amax ?
i) What are the position, velocity, and acceleration at t = ? s?
