Mr. H ignites the enthusiasm of the class with a homemade cannon demonstration. The 1.27-kg cannon is loaded with a 54-gram tennis ball and placed on the floor. Mr. H 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. Using video analysis, students determine that the cannon recoils backwards with a speed of 7.8 m/s. Determine the speed of the ball.
