Answer:

v = 3.97 m/s

Explanation:

The energy of the spring [tex]\frac{1}{2}kx^2[/tex] is converted into kinetic energy [tex]\frac{1}{2} mv^2[/tex].

[tex]\frac{1}{2} kx^2=\frac{1}{2} mv^2[/tex]

Solving for velocity v:

[tex]v = \sqrt{\frac{k}{m}} x[/tex]

[tex]v = 3.97\frac{m}{s}[/tex]

The velocity is 3.97m/s.

What is velocity?

Velocity is the directional speed of an object in motion as a demonstration of its rate of change in function as determined by a specific body of reference and as measured by the specific popularity of the time.

What is the velocity formula?

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.
