From hooks law
K=F/x = 93(2*10^-2)= 4650 N/m
Now applying conservation of energy
0.5 kx^2= 3.1
0.5 * 4650* x^2= 3.1
x= +3.65cm, -3.65cm

When a 0.62-kg mass is attached to a vertical spring, the spring stretches by 17 cm. How much mass must be attached to the spring to result in a 0.77-s period of oscillation?
When a 0.58-kg mass is attached to a vertical spring, the spring stretches by 15 cm. How much mass (total) must be attached to the spring to result in a 0.79-s period of oscillation?
A 2.60 kg mass is pushed against a horizontal spring of force constant 25.0 N/cm on a frictionless air table. The spring is attached to the tabletop, and the mass is not attached to the spring in any way. When the spring has been compressed enough to store 12.5 J of potential energy in it, the mass is suddenly released from rest. Part A Find the greatest speed the mass reaches. Part C What is the greatest acceleration of the...
A 2.25-kg mass is pushed against a horizontal spring of force constant 23.7 N/cm on a frictionless air table. The spring is attached to the tabletop, and the mass is not attached to the spring in any way.

(b) What is the greatest acceleration of the mass m/s2...
An object is attached to an ideal massless spring with spring constant of 0.20 N/cm and undergoes simple harmonic oscillations with a period of 1.57 seconds. What is the weight of the object ?
A 2.90 kg mass is pushed against a horizontal spring of force constant 26.0 N/cm on a frictionless air table. The spring is attached to the tabletop, and the mass is not attached to the spring in any way. When the spring has been compressed enough to store 15.0 J of potential energy in it, the mass is suddenly released from rest. Find the greatest speed the mass reaches and when does it occur? What is the greatest acceleration of...
A 12 cm long spring is attached to the ceiling. When a 2.6 kg mass is hung from it, the spring stretches to a length of 17 cm.(a) What is the spring constant k?
A positive charge q1 = 2.90 μc on a frictionless horizontal surface is attached to a spring of force constant k as in the figure shown below. when a charge of q2 =-9.100 μC is placed 9.50 cm away from the positive charge, the spring stretches by 5.00 mm, reducing the distance between charges to d = 9.00 cm. Find the value of k. The response you submitted has the wrong sign. N/m 1 42
