Does the speed of a ball rolling down a ramp change with the kind of material from which the ball is made?
The speed at which an object falls is not affected by its weight or mass, so a solid stone ball should fall just as quickly as a hollow wooden ball. But a ball made of a rougher material could slow it down. The material of the ball should only matter if affects how smooth the ball is.
A 3 kg cannon ball is fired from a cannon with a velocity of 90 ms what is the kinetic energy of the cannon ball?
1.2 x 10^4 J That is in Significant Figures
Does a cannon ball fly straight when fired?
no
How does the material of a ball affect how bouncy it is?
Think of it like this, if you pick up a ball that you drop on the floor, and squeeze that ball, if it is made out of a material like rubber, it is easy to squeeze, therefor it will bounce high. If the ball is made out of steel, then I personaly could not be able to squeeze it and it won't bounce very high or not bounce at all.
Does the material of the ball affect the way it bounces?
The material must influence the bounce of a ball: consider an inflated rubber ball versus an inflated aluminum ball. The difference might have to do with the elasticity of the material.
Why dont cannon balls explode when shot out OF CANNON?
Cannon balls are made of iron, which is a high-stress material. A high-stress material resists breaking. Because the cannon has an open end, and the iron ball resists being torn apart, the cannon ball is shot out instead.
When was the first cannon ball made?
The first cannon ball was made in the 3rd century BC in a place called Alexandra
When a ball is heated will the expansion be permanent?
That depends on the material from which the ball is made, if this material is elastic then no.

What is Trajectory?
A trajectory is the angle made with the horizontal when a projectile is fired. Suppose the projectile is a cannon ball. Assuming air is frictionless, that cannon ball will travel the greatest distance if the trajectory is 45 degrees from horizontal.
What is the size of a cannon ball?
the size of the cannon ball depends on the size of the cannon. civil war cannons had cannon balls about the size of a child's head, aprox 30cm across
When a cannon is fired will the cannon and cannon ball will have the same amount of kinetic energy?
Yes, both have the same energy, but because cannon is heavier the cannon ball gets more momentum and thus greater velocity.
