A mass m is gently placed on the end of a freely hanging spring. The mass then falls 29.8 cm before it stops and begins to rise. What is the frequency of the oscillation?
A mass m at the end of a spring vibrates with a frequency of 0.936 Hz. When an additional 558 g mass is added to m, the frequency is 0.634 Hz. What is the value of m?
A mass sitting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. 5.5 J of work is required to compressed the spring by 0.16 m. If the mass is released from rest with the spring compressed, it experiences a maximum accel...
A bungee jumper with mass 61.3 kg jumps from a high bridge. After reaching his lowest point, he oscillates up and down, hitting a low point eight more times in 31.8 s. He finally comes to rest 25.3 m below the level of the bridge. Calculate the spring constant of the bungee co...
