I would write:
momentum before shot = momentum after shot
0 = mv + MV
0 = 25*250 + 2000*V
The velocity of a cannonball after it is fired is affected by several factors including the initial force applied to the cannonball, the weight of the cannonball, the angle of the cannon's barrel, and the air resistance or drag on the cannonball as it travels through the air.
The angle of the cannon's barrel can greatly affect the velocity of the cannonball. When the cannon is fired at a higher angle, the cannonball will have a greater vertical velocity, but a lower horizontal velocity. Conversely, when the cannon is fired at a lower angle, the cannonball will have a higher horizontal velocity and a lower vertical velocity.
Yes, the weight of the cannonball does affect its velocity after it is fired. A heavier cannonball will require more force to be fired at the same velocity as a lighter cannonball. This is due to the conservation of momentum, where the force applied to the cannonball must be equal to the mass of the cannonball multiplied by its velocity.
Air resistance, also known as drag, can greatly affect the velocity of a cannonball after it is fired. As the cannonball travels through the air, it experiences the force of air resistance which acts in the opposite direction of its motion. This force can slow down the cannonball and decrease its velocity.
Yes, the velocity of a cannonball can be calculated using the formula: V = √(2gh), where V is the velocity, g is the acceleration due to gravity, and h is the height of the cannon. However, this formula assumes ideal conditions and does not take into account factors such as air resistance or the angle of the cannon's barrel.
