Can A hockey puck that slides across the ice at a constant speed be in equilibrium?

Non-sequitor. The friction of the ice, although minimal, causes a puck to travel at a decreasing speed. Given no friction, a puck could be said to have momentum equilibrium.

Is a hockey puck at equilibrium if it slides across the ice at a constant speed?
Yes.
Pull horizontally on a crate with a force of 140 N and it slides across the floor in a dynamic equilibrium How much friction is acting on the crate?
If the crate isn't accelerating ... i.e. sliding at a constant speed, not speeding up or slowing down ...then the forces on it are balanced. The pseudo-force of friction is 140N in the direction opposite toits speed.
How would the velocity of the book change if the applied force were equal to the sliding friction force?
The book slides with constant velocity.
What are the forces on a hockey puck as it slides away on ice?
Friction in the opposite direction to the direction of motion. Weight directly downwards. Reaction force directly upwards.
