PIRA 1D60.10 Projectile Motion: Howitzer and Tunnel
Instructions / Notes:
- A small cart - rolling at a constant speed -shoots a ball upwards before entering a tunnel
The ball travels in a parabola due to the combined horizontal motion of the launcher and a vertical launch of the cannon, which is pointed upward.
- The ball falls in the cart on the other side of the tunnel
Caution: A slow, steady motion must be used to launch the cart - to prevent it from crashing to the floor.
The small on/off dip switch is left in the "off" position, when the demo is not in use to prevent the coil from overheating and conserve battery life.
