Answer:
a) Instantaneous rate at which the force does work on the object = -6 W
b)
Explanation:
a) Given that
and
Instantaneous rate at which the force does work on the object is called power.
Power is the dot product of force and velocity.
Instantaneous rate at which the force does work on the object = -6 W
b) Here given that
Power = -12 W

Explanation:
you might be right on the north pacific but here is another option.
To solve this problem we will apply the principles of conservation of energy, for which we have to preserve the initial kinetic energy as elastic potential energy at the end of the movement. If said equality is maintained then we can affirm that,
Here,
m = mass
k = Spring constant
x = Displacement
v = Velocity
Rearranging to find the velocity,
Our values are,
Replacing our values we have,
Therefore the velocity is
