Question 1

In the figure below, a hoop (radius R = 1.0 m, mass = 2.0 kg) having four spokes of negligible mass is suspended from a pivot a distance d = .25 m above its center of mass. The angular frequency (in rad/s) for small oscillations is approximately

Question 2

John says that the value of the function cos[ω(t + T) + ϕ], obtained one period T after time t, is greater than cos(ωt + ϕ) by 2π. Larry says that it is greater by the addition of 1.00 to cos(ωt + ϕ). Which one, if either, is correct?

◦

John, because ωT = 2π.

◦

John, because ωT = 1 radian.

◦

Larry, because ωT = 2π.

◦

Larry, because ωT = 1 radian.

◦

Neither, because cos(θ + 2π) = cosθ.
