# How fast would a man's combat speed be if he kicked a Cannonball?

 P: 27 Ok another speed question thread. If a man who is 1400lbs jumped 5 feet in the air and performed a 360 degree spin and kicked a cannonball away,then how fast would he be? Assumptions: Lets assume that the CanonBall moves at 1500fps Lets assume that the Cannonball was 2 feet away from him before he performed this feat. Lets assume that his body is durable enough to do so.
 Mentor P: 12,001 Are you asking how fast his kick would be? I think we need a little more info, like the length of the mans legs.
 P: 27 Well no his movement as a whole but if you want you can calculate his kick.His feet would be about 3ft.Look,at the Op,for what his body would look like
 Math Emeritus Sci Advisor Thanks PF Gold P: 39,682 How fast would a man's combat speed be if he kicked a Cannonball? Well, we can say one thing- he will have lost a foot and would quickly bleed to death! (There are tales of soldiers in the American Civil War sticking a foot out to stop a cannon ball rolling slowly past at the end of its trajectory- not realizing that the ball still carried enough energy to take a foot off.)

Umm I put up a hypothetical setting.

I said lets assume that his body is durable enough to do so,so that means that his foot wont be taken off by the Canon-Ball if he "performed this feat".

This is based off of a fictional character btw.
 Emeritus Sci Advisor PF Gold P: 16,461 The problem is you are ascribing a number of magical properties to the situation, and asking what the physics would be. That tends not to work - you can't do a calculation "sometimes" ignoring reality.
