SUMMARY
The coefficient of kinetic friction (uk) for a 0.5kg puck sliding on ice can be determined using the given parameters: an initial speed of 20m/s and a displacement of 115m before coming to rest. The force of gravity acting on the puck is calculated as 4.9N. To find uk, one must apply kinematic equations alongside Newton's second law of motion, specifically relating the frictional force to the deceleration of the puck.
