Alittle kitten jumps from a tree and hits the ground 2.6 seconds later. with this information calculate the cat's velocity right before it hits the ground

The initial velocity is equal zero 
and the cat falls freely so the acceleration equal 9.81 m/s^2 
V = Vo + g * t 
V = 0 + (9.81 * 2.6) 
V = 25.5 m/s 

The correct answer is b

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
