In a closed system of a cannon and cannonball, which changes would both result in an increase in the kinetic energy of the cannonball when fired from the cannon?(1 point)

increase the mass of the cannon or decrease the mass of the cannonball

Both increasing the mass of the cannon and increasing the mass of the cannonball would result in an increase in the kinetic energy of the cannonball when fired from the cannon.

In a closed system of a cannon and cannonball, the kinetic energy of the cannonball can be increased by either increasing the mass of the cannon or decreasing the mass of the cannonball. The formula for kinetic energy is 1/2 * mass * velocity^2. When the mass of the cannonball increases, the kinetic energy will increase. Likewise, when the mass of the cannon decreases, the kinetic energy will also increase. Therefore, the correct answer is:

increase the mass of the cannon or decrease the mass of the cannonball
