At t=0, the displacement of a point x(0) in a linear oscillator is -8.6 cm, its velocity V(0)= -0.93 m/s and its acceleration a(0)= +48m/s2 . A- What is the angular frequency ω and the frequency f? B- What is the phase constant? C- What is the amplitude of the motion?

A pendulum's angular position is given by e = 0.0310 cos(mt), where e is in radians and w = 3.83 rad/s. Find the period (in s) and length (in m) of the pendulum. period -5.29 How does period depend on angular frequency? s length 5.29 How does the angular frequency of a pendulum depend on its length and the free-fall acceleration? m

You have a stationary mass attached to a compressed spring that is facing horizontal (on a frictionless plane). You give the mass a quick whack with a hammer, such that the mass has an initial velocity of 6.0 m/s. The amplitude of the oscillation of the mass is 4.0 m. How far is the mass from its starting position after 2.0 s? A) 0.50 m B) 0.56 m C) 0.78 m D) 1.0 m E) 1.1 m F) 2.0 m G) 2.3 m H) 4.0 m
