The correct option is (D)
In this case, there exist a restoring force acting on the oscillating object. The direction of this force must always point toward the equilibrium. As the time passes, the oscillations are decreases. It represents that the graph beween energy of block and time is oscillatory decay.
In the same time, the energy of spring block system is exponentialy decay with time.

A block of mass m = 2.00 kg is attached to a spring of force constant k = 465 N/m as shown in the figure below. The block is pulled to a position xi = 4.70 cm to the right of equilibrium and released from rest. A spring labeled k has its left end attached to a wall and its right end attached to a block labeled m. The block is initially at a location labeled x = 0. It...
You attach one end of a spring with a force constant k = 693 N/m to a wall and the other end to a mass m = 1.62 kg and set the mass-spring system into oscillation on a horizontal frictionless surface as shown in the figure. To put the system into oscillation, you pull the block to a position xi = 6.76 cm from equilibrium and release it. A horizontal spring labeled k is attached on its left end to...
A 750-gram block is attached to a spring as shown in the following diagram. The system is placed on a horizontal surface. The block is released at a distance of 0.15 m from the equilibrium position at Xo. It oscillates back and forth with a frequency of 0.25 Hz. Assume that the surface is frictionless. The oscillation is an SHM. (a) Find the spring constant. (b) Find the elastic P.E. in the system when the block is at the maximum...
A block of mass m, resting on a horizontal frictionless surface, is attached to one end of a spring; the other end is fixed to a wall. It takes 3.6 J of work to compress the spring by 13 cm; then it is released from rest. It experiences a maximum acceleration of 15 m/s2. Find the value of (a) the mass of the block. As the block passes through its equilibrium position, a lump of putty of mass mi -...

A 2.00-kg object is free to slide on a horizontal surface. The
object is attached to a spring of spring constant 300 N/m , and the
other end of the spring is attached to a wall. The object is pulled
in the direction away from the wall until the spring is stretched
50.0 mm from its relaxed position. The object is not released from
rest, but is instead given an initial velocity of 2.50 m/s away
from the wall. Ignore...

Q1-(25 pts) A block of mass m is on a horizontal surface and is attached to a spring whose other end is fixed. The spring constant is k. The coefficient of kinetic friction between the block and the horizontal surface is u. A force Facts on the block always making an angle with the horizontal, as shown in the figure. The magnitude of the force is adjusted so that the block moves with constant speed v on the surface from...
A 0.20-kg block is attached to a light, horizontal spring of stiffness 64 N/m; the other end of the spring is attached to a wall; the block is free to oscillate on a frictionless, horizontal surface. What is the time interval for one complete cycle? If the block is released from rest when the spring is stretched from its relaxed length by 3.0 cm, how much mechanical energy does the system possess? What is the maximum speed of the block?...
Q3-(25 pts) A block of mass m is attached to an ideal spring with rest (equilibrium) length L and spring constant k on the x axis. m other end of the spring is fixed to a wall Initially, the spring is compressed by an amount L/2 and another block of mass 2m is placed in front of the first block (they are not attached). The system is released at t 0 from rest. Ignore friction and the sizes of the...
