## Homework Equations

## The Attempt at a Solution

Ok, i imagined the situation as half a projectile. with the cat traveling the hypotenuse of the triangle that can be formed (2.5 and 3.5 base). I know vi = 0 at highest point of a projectile and i know that the distance is 4.3 (pythagoras) i used kinematics ( d = vit + 1/2at^2) and get an answer of 0.81..
