Constant Period of a Mass on a Spring Easy A mass is hanging on a spring and vibrating up and down with a period that you can measure. You replace the spring with a spring that has twice the original spring constant. Which of the following corresponding changes must also occur if the period of the spring is to remain the same? Elimination Tool Double the mass on the spring. B Double the amplitude of the spring's vibration Put half...

A mass m at the end of a spring oscillates with a frequency of 0.73 Hz . When an additional 750 g mass is added to m, the frequency is 0.59 Hz . What is the value of m?
(1 point) Suppose a spring with spring constant 7 N/m is horizontal and has one end attached to a wall and the other end attached to a mass. You want to use the spring to weigh items. You put the spring into motion and find the frequency to be 0.9 Hz (cycles per second). What is the mass? Assume there is no friction. Mass = help (units)
