physics
A mass of 0.394 kg is attached to a spring with a spring constant of 224.2 N/m. Its oscillation is damped, with damping constant b = 14.0 kg/s. What is the angular frequency of this damped oscillation? ω = rad/s

physics
When a mass is attached to a vertical spring, the spring is stretched a distance d. The mass is then pulled down from this position and released. It undergoes 52 oscillations in 28.3 s. What was the distance d?

Calculate the angular speed of the rod, the vertical acceleration of the moving end of the rod, and the normal force exerted by the table on the rod as it makes an angle θ = 49.6° with respect to the vertical. b) If the rod falls onto the table without slipping, find ...

You are flying to Chicago for a weekend away from the books. In your last physics class, you learned that the airflow over the wings of the plane creates a lift force, which acts perpendicular to the wings. When the plane is flying level, the upward lift force exactly balances...
