If I had a mass on a string and rotated it at constant velocity how would its velocity change if the string snapped?

I believe you meant that you had an object on a string that revolved around an axis at a constant velocity. If that is the case, under friction free conditions, when the string snaps, it's velocity would not change, only its direction of movement. The centripetal force that was keeping the mass revolving around the axis would converted into centrifugal force that would make it travel in a straight line away from the axis.

If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Why achanging velocity cannot maintaining constant speed?
A changing velocity can maintain constant speed if the motion is circular. The constant change in direction is a change in velocity, even if the speed is constant.
How is constant velocity different from changing velocity?
"Constant" means that it doesn't change.
Can an object traveling at constant velocity have acceleration why?
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
Can you have constant speed but change in velocity?
Velocity will always change in speed.
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
Can a velocity of a body change its speed is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
Can speed of a body change if its velocity is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this.

Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
Does constant speed give you constant velocity?
No. The speed can be consant but direction can change and thus the velocity changes.
If A car moves at constant speed also moving at constant velocity?
Not necessarily. Constant velocity also means no change in direction.
Can an object be accelerating with constant velocity?
No, since acceleration is defined as a change in velocity. If there is no change, there is no acceleration.
Why is constant velocity not acceleration?
Acceleration is the rate of change in velocity. When velocity is constant, it is NOT CHANGING so acceleration is negligible or ZERO or non-existent.
