A block weighing 14.0 N is attached to the lower end of a vertical spring (k = 238.0 N/m), the other end of which is attached to a ceiling. The block oscillates vertically and has a kinetic energy of 1.90 J as it passes through the point at which the spring is unstretched. (a) What is the period of the oscillation? (b) Use the law of conservation of energy to determine the maximum distance the block moves above the point...
Problem 6. A block of mass 400 grams is suspended from a vertical spring of force constant 25.0N/m. (a) How much is the stretch in the spring when the system is in equilibrium? The block is pulled a distance of 20.0 cm below its equilibrium position and released (b) What is the total energy of the system when the block is released? (Take the gravitational potential energy to be zero in the equilibrium position.) (c) What is the speed of...
A block of mass m = 2 kg slides back and forth on a frictionless horizontal track. It is attached to a spring with a relaxed length of L = 3 m and a spring constant k = 8 N/m. The spring is initially vertical, which is its the relaxed postion but then the block is pulled d = 3 m to one side 1. By what length is the spring extended? _______m 2. What is the potential energy stored...

At the spring meeting of the American Potential Energy Society, a debate erupts over the choice of a reference point for elastic potential energy. One faction (group #1) feels it is only natural to choose the reference point at the location at which the spring is neither stretched nor compressed and to measure the elastic potential energy relative to that unstrained configuration. Another faction (group #2), whose members always like to think "outside of the box", wants to choose the...
OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
