PIRA: 1M40.65

Equipment List

  • Pasco projectile launcher
  • plunger
  • plastic balls
  • small C-clamp

Instructions

  1. Clamp the launcher to table. Using the plunger, push ball in to short range setting. Point the launcher straight up and fire. Measure the height.
  2. Turn the launcher to horizontal and fire again from the short range. Use the height and range of this ball to determine initial velocity. (t=2y/g and vo=x/t)
  3. Using conservation of energy calculate the maximum height of a vertical shot. Compare with the value from #1.
  4.  Set the launcher to various angles to find the angle which gives maximum range
