SUMMARY
A hockey puck sliding on a frozen lake comes to rest after traveling 175 meters with an initial velocity of 1.9 m/s. The correct acceleration, calculated using the kinematic equation \( a = \frac{\Delta v}{\Delta t} \), is -0.002857142 m/s². The time taken for the puck to stop is approximately 350 seconds. The discussion emphasizes the importance of understanding the definitions of acceleration and the correct application of kinematic equations.
