It took me a while to catch on . . .

An athlete uses a sling to throw a projectile at a target 15m away.

He spins the sling in a circle above his head, then releases the projectile.

If the sling is 1 m long, at what distance from the target must the athlete

release the projectile so that it will hit the target?

Answer: ~14.97m Code:

The athlete is at .

The target is at

The sling is 1 meter long: .

When the projectile is released at , it flies off *tangent* to the circle.

. . Hence: .

We want the distance

From Pythagorus: .

Therefore: . m.
