An object, whose mass is 0.700 kg, is attached to a spring with a force constant of 104 N/m. The object rests upon a frictionless, horizontal surface
(shown in the figure below).
m
The object is pulled to the right a distance A = 0.110 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?
O Away from the equilibrium position (i.e., to the right in the figure).
O Toward the equilibrium position (i.e., to the left in the figure).
The direction is not defined (i.e., the acceleration is zero).
You cannot tell without more information.
