Arevolutionary war cannon, with a mass of 2260 kg, fires a 15.5 kg ball horizontally. the cannonball has a speed of 109 m/s after it has left the barrel. the cannon carriage is on a flat platform and is free to roll horizontally. what is the speed of the cannon immediately after it was fired? answer in units of m/s.

The gain in velocity is 0.37m/s

Explanation:

We need solve this problem though the conservation of momentum. That is,

Using the equation to find ,

Using the conservation of energy equation, we have,

Now this energy over the cannonball

The gain in velocity is 0.37m/s

i think the answer would be b

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
