What Happens When You Fire A Ball At 60 MPH Out Of A Moving Truck

It’s one thing to have the laws of physics explained to you, but it’s another to actually see it in action. And while it is essential to understand how it happens, being involved in the process makes science more exciting.

The legendary Mythbusters were out to prove how the laws of physics work in this clip when they demonstrated what happens when a soccer ball is fired at 60 mph from a cannon mounted on a truck traveling in the opposite direction at the same speed.

Mythbusters fire a cannon ball out of the back of a car at the same velocity that the car is moving. If you’re good at math, you can suspect what is going to happen.


And while the answer is pretty obvious, going to all the trouble of proving it and actually see the ball drop straight down is immensely satisfying.
