part 1 of 4 10 points

An M = 1.89 kg mass is suspended on a

k = 566000 N/m spring. The mass oscillates

up-and-down from the equilibrium position

yeq = 0 according to

y(t) = A sin(!t + 0).

Calculate the angular frequency ! of the

oscillating mass.

Answer in units of s−1.

Question 7, chap 15, sect 3.

part 2 of 4 10 points

At time t0 = 0 the mass happens to be at

y0 = 15.2 cm and moving upward at velocity

v0 = +309 m/s. (Mind the units!)

Calculate the amplitude A of the oscillating

mass.

Answer in units of cm.
