Figure 15-34 shows block 1 of mass sliding to the right over a frictionless elevated surface at a speed of. The block undergoes an elastic collision with stationary block, which is attached to a spring of spring constant1208.5N/m. (Assume that the spring does not affect the collision.) After the collision, block2 oscillates in SHM with a period of 0.140s, and block 1 slides off the opposite end of the elevated surface, landing a distance from the base of that surface after falling height .

A 95 kgsolid sphere with a 15 cmradius is suspended by a vertical wire. A torque of 0.20 N.mis required to rotate the sphere through an angle of 0.85 radand then maintain that orientation. What is the period of the oscillations that result when the sphere is then released?
The vibration frequencies of atoms in solids at normal temperatures are of the order of. Imagine the atoms to be connected to one another by springs. Suppose that a single silver atom in a solid vibrates with this frequency and that all the other atoms are at rest. Compute the effective spring constant. One mole of silver (atoms) has a mass of 108 g.
In fig.15-28, a spring鈥揵lock system is put into SHM in two experiments. In the first, the block is pulled from the equilibrium position through a displacement and then released. In the second, it is pulled from the equilibrium position through a greater displacement and then released. Are the (a) amplitude, (b) period, (c) frequency, (d) maximum kinetic energy, and (e) maximum potential energy in the second experiment greater than, less than, or the same as those in the first experiment?
Two particles execute simple harmonic motion of the same amplitude and frequency along close parallel lines. They pass each other moving in opposite directions each time their displacement is half their amplitude. What is their phase difference?
