Mr. Chowder adds the fuel, waits for its vapors to fill the reaction chamber and then brings a match nearby. The explosion stuns the crowd and propels the ball forward. A photogate measurement determines that the cannon recoiled backwards with a speed of 7.71 m/s. Determine the speed of the ball. BallSpeed m/s Mg Attempts:ooo m Help Links 1A\\ 0 1:: II '_ 2.
