Monkey And Hunter

An interesting projectile experiment med as monkey and hunter consists of a monkey model, a gun in which a tennis ball is used as bullet, an electromagnet and a flexible wire. A spring loaded gun fires bullet (table tennis ball) at a monkey model supported from a tiny electromagnet clamped on a laboratory stand. The electromagnet is switched off at the same instant as the bullet leaves the gun. Both monkey and bullet will release at the same rate and so the bullet always hits the monkey thus proving that perpendicular motions are independent. The system has everything required except a low voltage power supply and laboratory stand for the electromagnet. Working range for the experiment is 3m maximum.
