Problem 6. A mass of 1.00 kg is hung from the ceiling by an ideal spring. When a mass of 0.500 kg is added to the original mass, the spring stretches by an additional 0.933 cm. (a) What is the force constant of the spring? (b) By how much did the spring stretch when only the 1.00kg mass was hung from it? The system (with the 1.50kg mass) is now set in oscillation with an amplitude of 2.20cm. (c) What...

4. A 6-kg block (my), initially at rest on a rough shelf, is connected to a 4-kg block (m2) that hangs by an inextensible string of negligible mass passing over a pulley. The uniform disk-shaped pulley, having a mass of 3.0-kg and a radius of 10 cm, rotates about the symmetry axis through its center. The 6-kg block, which is attached to the spring, is initially pushed against the spring compressing it a distance of 30 cm from its equilibrium...

An ideal spring hangs from the ceiling. A 1.45 kg mass is hung from the spring, stretching the spring a distance d 0.0845 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L-0.0295 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position? kinetic energy Equilibrium position

An ideal spring hangs from the ceiling. A 1.85 kg mass is hung from the spring, stretching the spring a distance d = 0.0905 m from its original length when it reaches equilibrium. The mass is then lifted up a distance 0.0265 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position? d kinetic energy J Equilibrium position

An ideal spring hangs from the ceiling. A 2.15 kg mass is hung from the spring, stretching the spring a distance d = 0.0865 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0235 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position?
A pendulum of a mass mp = 3.60 kg hanging at the bottom end of a...
A pendulum of a mass mp = 3.60 kg hanging at the bottom end of a massless rod of length ℓ = 0.60 m has a frictionless pivot at its top end. As shown in the above figure, a bullet of mass mb = 0.50 kg, moving with a horizontal velocity vb, impacts the pendulum and becomes embedded. The pendulum then swings to rest at its topmost position converting all of its kinetic energy into potential energy. (a) Use the...
