Vertical Spring

An ornament of mass 40.0 g is attached to a vertical ideal spring with a force constant (spring constant) of 20.0 N/m. The ornament is then lowered very slowly until the spring stops stretching. How much does the spring stretch?

• 0.00200 m
• 0.0196 m
• 0.0816 m
• 0.800 m

A force of  30 N stretches a very light ideal spring 0.73 m from equilibrium. What is the force constant (spring constant) of the spring?

• 41 N/m
• 22 N/m
• 34 N/m
• 46 N/m

An object attached to an ideal spring executes simple harmonic motion. If you want to double its total energy, you could

• double the amplitude of vibration
• double the force constant (spring constant) of the spring
• double both the amplitude and force constant (spring constant).
• double the mass

An object is attached to a vertical spring and bobs up and down between points A and B.  Where is the object located when its kinetic energy is a minimum?

• at either A or B
• midway between A and B
• one-third of the way between A and B
• one-fourth of the way between A and B

A 0.39-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is  570 N/m. The block is pulled from its equilibrium position at x = 0.000 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. When the position of the block is x=0.057 m its kinetic energy is closest to

• 0.90 J.
• 0.84 J.
• 0.95 J.
• 1.0 J
