An object, whose mass is 0.580 kg, is attached to a spring with a force constant of 112 N/m. The object rests upon a frictionless, horizontal surface (shown in the figure below). An object labeled m is attached to the right end of a horizontal spring, and the left end of the spring is attached to a wall. The spring is stretched horizontally such that the object is displaced by a distance A to the right of its equilibrium position. The object is pulled to the right a distance A = 0.130 m from its equilibrium position (the vertical dashed line) and held motionless. The object is then released from rest. (a) At the instant of release, what is the magnitude of the spring force (in N) acting upon the object? N (b) At that very instant, what is the magnitude of the object's acceleration (in m/s2)? m/s2 (c) In what direction does the acceleration vector point at the instant of release? The direction is not defined (i.e., the acceleration is zero). Away from the equilibrium position (i.e., to the right in the figure). Toward the equilibrium position (i.e., to the left in the figure). You cannot tell without more information.

An object, whose mass is 0.580 kg, is attached to a spring with a force constant of 112 N/m. The object rests upon a frictionless, horizontal surface (shown in the figure below).
An object labeled m is attached to the right end of a horizontal spring, and the left end of the spring is attached to a wall. The spring is stretched horizontally such that the object is displaced by a distance A to the right of its equilibrium position.
The object is pulled to the right a distance A = 0.130 m from its equilibrium position (the vertical dashed line) and held motionless. The object is then released from rest.
(a)
At the instant of release, what is the magnitude of the spring force (in N) acting upon the object? N
(b)
At that very instant, what is the magnitude of the object's acceleration (in m/s2)?
m/s2
(c)
In what direction does the acceleration vector point at the instant of release?
The direction is not defined (i.e., the acceleration is zero).
Away from the equilibrium position (i.e., to the right in the figure).
Toward the equilibrium position (i.e., to the left in the figure).
You cannot tell without more information.
