The same explosive charge is used, so the total energy of the cannon plus cannonball system remains the same. disregarding friction, how much faster would the ball travel if the cannon were mounted rigidly and all other parameters remained the same? answer in units of m/s.

we need to know the time interval during which the force acts. impulse of force = momentum change

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
