You are incorrect aspvenom.
The linear velocity
is the speed and the direction of the object at any given time. An object going at a constant speed in a circular path absolutely
has a speed and a direction at any given time.
So yes, this object has a non-zero linear velocity.
The linear acceleration
is the change in the linear velocity. Since the direction the object is moving is changing, there is absolutely a linear acceleration.
The angular velocity
is the angular speed (i.e. the number of radians the object is travelling around the circle per second) with a direction along the axis of rotation. There is an angular velocity for this object at constant speed around a circular path, but it isn't changing
because at constant speed the object travels the same number of radians each second, and since the direction is the axis of rotation it doesn't change.
And of course, since the angular velocity isn't changing, the angular acceleration
for constant speed circular motion is zero. If the speed of the object is changing, then that would mean a non-zero angular acceleration.
This is math. There is a right answer.
If your intuition doesn't match the right answer, then your intuition is wrong.
Actually, this is rather simple math. These answers are things you probably learned and forgot in high school.
