finding velocity?

Question

i need to find the velocity of a bouncing ball in equation form, and a written answer how would i do that.
best correct answer (like i would know) will recieve extra points.

dont just right dumb stuff to get some points, and dont give me wrong answerers on purpose i will know i do know some about physics. please and thank you

Answer 1

V=V0+gt
g is acceleration due to gravity.

Answer 2

Velocity and bouncing ball seem like a good candidate
for Hooke's Law and using spring style potential energy.
Hooke's Law:
f=-kx ; where f is the force, k is the constant for the spring,
and x is the distance from spring equilibrium.

PE=0.5kx^2

KE=0.5mv^2

When the ball strikes the ground it deforms. When this
happens it takes on the properties of a spring which
is what causes it to rebound back into the air.

Assume that the bouncing ball continues to bounce
indefinitely with no external forces which means that
the PE and the KE are totally conserved within the
bouncing system process. Therefore,

KE=PE at the respective max compression(deform)
and max height of the ball.

0.5mv^2=0.5kx^2
mv^2=kx^2
v^2=kx^2/m
v=sqrt(kx^2/m)
