The ball has some kinetic energy at it's maximum height which you've neglected.

Edit:
I said you would be right if it was launched straight up, but that's not true. Sorry, I'm tired.
(If it was launched straight up you would use 8.2m for "h" not 12.9m)

 

[ASHU]

v=47.6 m/s
Is that the right answer?
calculate vertical component and horizontal component separately.

 

[Nathanael]

v=47.6 m/s
Is that the right answer?

Yes.

Kinetic energy is a fundamental concept in physics that refers to the energy an object possesses due to its motion. In the context of projectiles, the kinetic energy is the energy that the projectile has due to its motion through the air. It is calculated using the equation KE = 1/2 * m * v^2, where m is the mass of the projectile and v is its velocity. This means that the kinetic energy of a projectile is directly proportional to its mass and the square of its velocity. As a scientist, it is important to understand the concept of kinetic energy in order to accurately predict and analyze the behavior of projectiles in motion.
