Previous Next Monkey and Hunter # 1D60.30
Description: This demonstration shows the independance of vertical and horizontal motion. Both objects are accelerated in their vertical motion, but the horizontal motion is unaffected, so aiming directly at the target will get you a hit on the target. Due to the violent and cruel nature of this demonstration, North Carolina State University does not condone the shooting of monkeys. The demo room has two items it considers Politically Correct to shoot at; (1) a metal target, (2) the UNC-CH mascot. Instructions: This demo will be set and aimed when you arrive. The aiming will have been done using the metal plate, so the use of the UNC Ram will potentially need some adjustments. (1) Place the ball in the cannon; (2) Hold the back of the cannon to steady it; (3) Use the plunger and force the ball all the way back; (4) Switch the control box over to "arm" (a red light will light); (5) Hang the target from the magnet; (6) Pull up on the yellow launching string slowly. (7) Switch control box to "disarm." Repeat steps 1-7 for another shot. Hazards: The target is held by a small permanent magnet that releases the target when a pulse of current disrupts the feild. If the support is shaken, the target may fall. Please do not linger beneath the target. Parts: Shoot the monkey apparatus Metal target Tarheel Purchased/Built: purchased Quant. in Demo Room: 2 Source: Pasco Scientific Demo References The Video Encyclopedia of Physics Demonstrations Disc 02-02 The apparatus consists of a blow gun with dowel projectile and electromagnetic release.
