A spring hangs ( unstretched) from a support. A 300 gram mass is suspended from the spring and allowed to reach equilibrium. If the mass is pulled below this equilibrium position and released, what is its period of oscillation? (the spring stretches to 30.0 cm)
Please, show me.
mg=kx
k=0.3*9.8/0.3 = 9.8 Nm
time period = 1/2pi sqrt(K/m)
=1/2pisqrt(9.8/0.3) =0.91s
Spring force= gravitational force
kx=mg=> k=0.3*9.8/0.3=9.8 N/m
w=sqrt(k/m)=(9.8/0.3)^(0.5)=5.71 rad
Time period T=2*pi/w=2*pi/5.71=1.1 s

A spring stretches 25.7 cm from equilibrium when it hangs vertically with a 1.56 kg mass attached to the spring. a) What is the spring constant of the spring? b) If the spring is pulled further down and released, what is the frequency of the oscillation?

A spring with a mass on the end of it hangs in equilibrium a distance of 0.4200m above the floor. The mas is pulled down a distance of 0.0600m below the original position, released, and allowed to oscillate. How high above the floor is the mass at the highest point in its oscillation? Show work.
A spring with a spring constant 15.0 N/m hangs from the ceiling. A ball is suspended from the spring and allowed to come to rest. It is then pulled down 6.00 cm and released. If the ball makes 30 oscillations in 20.0 s, what is its mass?
Q2. A mass of 300 g is attached to a spring hanging from the ceiling. The spring stretches 20 cm when the mass is added. What is the spring constant of the spring? If the mass is now pulled 8 cm below it’s new equilibrium position, what will be the frequency of the oscillation What is the maximum speed of the mass? At what position will it have a speed that is one third of the maximum speed? What is...
A spring with spring constant 14.9 N/m hangs from the ceiling. A ball is suspended from the spring and allowed to come to rest. It is then pulled down 4.00 cm and released. The ball makes 28.0 oscillations in 21.0 seconds. What is the mass of the ball? What is the maximum speed?
A spring with spring constant 12.2 N/m hangs from the ceiling. A ball is suspended from the spring and allowed to come to rest. It is then pulled down 10.0 cm and released. The ball makes 29.0 oscillations in 21.0 seconds. What is the mass of the ball? What is the maximum speed?
A proud deep-sea fisherman hangs a fish of mass 61.0 kg from an ideal spring having negligible mass. The fish stretches the spring a distance of 0.119 m What is the force constant of the spring? What is the period of oscillation of the fish if it is pulled down and released?
A spring with a spring constant = 15.0 N/m hangs from the ceiling. A ball is suspended from the spring and allowed to come to rest. It is then pulled down 6.00 cm and released. If the ball makes 30 oscillations in 20.0 s, what is its mass?
A 50-cm-long spring is suspended from the ceiling. A 250 g mass is connected to the end and held at rest with the spring unstretched. The mass is released and falls, stretching the spring by 18 cm before coming to rest at its lowest point. It then continues to oscillate vertically. a. What is the spring constant? b. What is the amplitude of the oscillation? c. What is the frequency of the oscillation?
