Answer:
The correct answer is:
between kinetic energy and elastic potential energy.
In fact, the total mechanical energy of the system is given by:
where
is the elastic potential energy, with k being the spring constant and x being the compression/stretching of the spring, and
is the kinetic energy, with m being the mass of the toy and v being its speed.
When the spring is compressed, the elastic potential energy U is maximum (since x is maximum), and the kinetic energy is zero(since the speed is zero). As the spring is released, the elastic potential energy U decreases (because x decreases), and the kinetic energy K increases (since the speed of the toy v increases).

Answer:
d.Kinetic energy and elastic potential energy
Explanation:
As we know that the toy is pressed against the spring initially
so the energy is stored inside the spring
this energy is given by
[tex]E = \frac{1]{2}kx^2[/tex]
here we have
k = spring constant
x = compression in spring
when this toy is released then it is projected up by the spring with certain speed
so here we can say that energy is converted into kinetic energy
so here we can say
[tex]\frac{1}{2}kx^2 = \frac{1}{2}mv^2[/tex]
so here we will have
d.Kinetic energy and elastic potential energy
