This is the trough mirror and a Fresnel Lens set. The water was shot in with a hose to produce flash steam. Ball bearing were used as ammo. A few modifications from this learning experience and we can launch 200 yards.

A 2180 kg cannon fires a 17.3 kg ball horizontally?

Posted on February 13, 2010 by admin| 3 Comments

The cannonball has a speed of 133 m/s after it left the barrel. The cannon carriage is on a flat platform and is free to roll horizontally.
What is the speed of the cannon just after it was fired in units of m/s?

Assume the same explosive charge is used and the total energy of the cannon plus the cannonball system remains the same. Disregard friction. How much FASTER would the ball travel if the cannon was mounted rigidly but all other parameters were the same (in units of m/s)?
