Title
One end of a 50-kg mass is attached to two vertical springs in parallel. Each spring has a spring constant of 20 N/m. When the spring is pulled back and released, what is the systems period?
A steel ball with a mass of 100 g is dropped onto a steel plate. The collision is perfectly elastic. From what height must the ball be dropped for the vibrating system to have a bounce period of 2.0 s?
A spring with a constant of 300 N/m is stretched by 0.5 m. What is the force on the spring?
The displacement (in centimeters) of the vibrating cone of a large loudspeaker is represented by the equation x= 2.0 cos(150t), where t is the time in seconds. What distance does the tip of the cone move in half a period?
A blue light wave vibrates at 6.98 X 10^14 Hz. What is its period of vibration?
