@sophiecentaur -- OP is asking for force, not KE, if I'm reading correctly. And yes, agreed that google rules here :-) @LT72884 -- to try further clarification, the acceleration you want is the negative acceleration (assuming positive is in direction of BB) experienced by the BB when it slows...

Here's a useful reference: http://hyperphysics.phy-astr.gsu.edu/hbase/impulse.html. That is useful if you know how deeply the impact of paintball or BB pushes into your body, e.g. you can start with an assumption of 100% of the projectile's diameter (so 17.2mm or 6mm, right?). Read the part...

Blowing across the water introduces a temperature gradient between the water and its environment. Now, assuming your breath is cooler than the water, thermodynamics tells us that the system will move towards equilibrium via more water molecules escaping the water and as such removing heat from...

Let's try an analogy: say for sake of argument that a tennis ball has a mass of 0.05 kg. Now that could be 0.04996, or maybe 0.533, but it doesn't really matter. You can only have an integer multiple of tennis balls in your possession. Unless of course, you slice one open and then you could have...
