I am Science Trainer Ken Kuwako. For me, every day is an experiment.<\/strong><\/span><\/p>\n

Imagine a slightly timid monkey perched high in a tree. He is so sensitive to loud noises that the moment he hears a “Bang!”, he let go of the branch and starts to fall. Now, imagine you are aiming a ball at him from the ground. The second you fire with a “Bang!”, the monkey begins his descent.<\/strong> It sounds like hitting a moving target would be nearly impossible, doesn’t it? But actually, there is a bit of physics magic hidden in the laws of motion. Today, I want to introduce you to the fascinating world of Monkey Hunting<\/strong>, one of the most popular topics in high school physics!<\/p>\n

The Mystery of the Monkey Hunter Problem<\/h3>\n

“Monkey Hunting” is a world-famous thought experiment in the realm of physics.<\/p>\n

The puzzle is simple: for a monkey that starts a free fall with zero initial velocity<\/strong> from a tree, what angle and what speed should you fire the projectile at to ensure a hit?<\/strong><\/p>\n

\"\"<\/p>\n

If the target stayed still, it would be easy. But since the monkey drops the very instant you fire, should you aim a little lower? Or is there a different secret? (I have included a challenge at the end of this post for those who want to solve it mathematically!)<\/p>\n

Try it Yourself with This Simulation!<\/h3>\n

Before we get into the theory, the best way to understand is to try it! In the program I built, I have placed the monkey at a 45-degree angle. At what angle should you aim to hit him? Give it a shot here!<\/a><\/p>\n
