The Physics of Kicking a Cat

As most people know, I can't stand cats, and constantly joke about kicking them. So, I thought it would be appropriate if I did a blog post on it!!

I am by far not athletic, so top speed I could probably kick a soccer ball at 15 m/s or 33.354 mi/hr (This is the average low for kids 11-17 <_< ). I also don't kick at much of an angle, but for this we'll say 20 degrees.

So here's the math:

y- component:

height: ?

acceleration: 9.8

velocity initial: 15sin20= 5.13

velocity final: 0

time:?

vf= vo + at

0= 5.13 + -9.8t

5.13= 9.8t

t= .5235 --> Total Time: 1.047 seconds

Y= vot + .5at2

Y= 5.13(.5235) + .5(9.8)(.5235)2

Y= 2.686+ 1.343

Y= 4.028 meters --> 13.22 feet

x-component:

velocity: 15cos20= 14.10

time: 1.047

distance: ?

x= vt

x= 14.1(1.047)

x= 14.758 meters --> 48.42 feet

DANG! That's far. Now I wanna try this. Anyone got a cat I can borrow?

Very violent, but I have learned that cats end up at the wrong end of many physics demonstrations by now...I wonder why cats and not any other animals?

Hahaha well played Mr. Fullerton.  But this is pretty interesting!  I don't have a cat, but you can borrow one of my younger siblings I guess...
