Final answer:
The question about a hockey puck marking a brain appears to be a typo; instead, we can focus on physics concepts related to the puck's motion, such as force, momentum, and displacement.
Step-by-step explanation:
The question asks if a hockey puck will mark a brain when it travels 12 feet in 2 seconds, bounces off a wall, and then takes 3 seconds to return to its starting point before being stopped. However, this seems to be a typo or a misunderstanding within the question, as pucks and brains are not typically related in physics problems. The question should focus on the motion of the puck and the forces involved during its travel and collision with the wall. We can address physics concepts such as momentum, force, and displacement through problems such as:
- Calculating the average force exerted by a wall on a puck during a collision.
- Calculating the magnitude and direction of the change in momentum of a puck.
- Describing the displacement over time for a puck moving back and forth.
These types of physics questions often involve using equations of motion, Newton's laws, and principles of conservation.
