Refer to Conceptual Example 2 as an aid in solving this problem.
A 120 coil spring has a spring constant of 412 N/m. It is cut into
4 shorter springs, each of which has 30 coils. One end of a 30 coil
spring is attached to a wall. An object of mass 43 kg is attached
to the other end of the spring, and the system is set into
horizontal oscillation. What is the angular frequency of the
motion?
rad/s

A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall whle the other end is connected to a movable object. The spring and object are compressed by 0.082 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 11.9 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.041 m relative to its unstrained length? _______ m/s

Review Conceptual Example 3 and the drawing as an aid in solving this problem. A conducting rod slides down between two frictionless vertical copper tracks at a constant speed of 4.1 m/s perpendicular to a 0.47-T magnetic field. The resistance of the rod and tracks is negligible. The rod maintains electrical contact with the tracks at all times and has a length of 1.6 m. A 0.98- resistor is attached between the tops of the tracks. Find the change in...

A 600-g object is attached to a spring with a force constant of 2.4 N/m. The object rests on a horizontal surface that has a viscous, oily substance spread evenly on it. The object is pulled 15 cm to the right of the equilibrium position and set into harmonic motion. After 3 s, the amplitude has fallen to 7 cm due to frictional losses in the oil. Calculate the following. a. The natural frequency of the system b. The damping...
