Depends on the cannon and the charge.
Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!
Yes.
The speed will depend on its initial velocity and any forces acting on it.
they would be in a vacuum
If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.
the speed it moved at was very close to a cannonballs speed after leaving a cannon
The range of a projectile is given by R=(v2/g)Sin(2Theta) so for an angle of 30 and an initial speed of 100 m/s: R=(1002/9.8)Sin(60)=(10000/9.8)(sqr3/2)= 883.7 m ^^know-it-all! :@ ^^^^^^^^^;)
initial speed means first
Initial speed is the original, beginning speed of an object.
The energy needed to move a cannonball is created by burning fuel--usually gunpowder but nothing says they couldn't make a cannon that burned propane to fire projectiles. Anyway, if you're firing a round the speed of that cannonball is determined in part by how long the energy's being applied to it. The longer the barrel is, the longer the energy will be applied and the faster the cannonball will go.
Its initial speed is less than its final speed.

Cannonball puno Cannonball - Cannonball Puno - Tree
Bob sed Shirley's initial speed is eight million mph
Yes.
Cannonball prutas Cannonball meaning cannonball Prutas meaning fruit
If a car is speeding up, it's initial speed is LOWER than it's final speed.
