It's a negative value because the negative sign on the spring's force means the force exerted opposes the spring's displacement

Explanation:

Hooke's law :

According to the Hooke's law, The force is the directly proportional to the displacement of the string.

On the other hand,

In a simple harmonic motion, The restoring force is directly proportional to the displacement and acts in the opposite direction to that of displacement.

The restoring force is defined as,

F\propto -x

F = -kx

Where,

F = restoring force

k = restoring constant

x = displacement

The negative sign shows the force opposes the string's displacement

Answer:

Mass of the box is 25kg

Explanation:

From Newton's second law of motion

Force= mass. acceleration

With the symbol

F=m.a

m=F/a      m=(50N)/(2m/s²)

                m=25kg
