Question

a little 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

Answer 1

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
