Final answer:
Both angular momentum and linear momentum are likely to be conserved when an ice hockey puck strikes a hockey stick lying flat on the ice; however, kinetic energy may not be fully conserved due to the possibility of an inelastic collision. The correct answer is a) Angular momentum and linear momentum.
Step-by-step explanation:
If an ice hockey puck strikes a hockey stick lying flat on the ice and free to move in any direction, the quantities likely to be conserved are angular momentum and linear momentum.
The conservation of linear momentum occurs because the net external force on the puck-stick system is zero, assuming no external forces like friction act on the system.
As for angular momentum, it is conserved in the absence of any net external torque, which is assumed to be the case if the stick is free to move in any direction and no other forces are acting on it.
However, because the collision between the puck and the stick may not be perfectly elastic, kinetic energy may not be fully conserved; some of that energy could be converted into other forms such as heat or sound.
