Short track speed skating (MATLAB) Measure the record of a player who has passed the finish line through conditions in MATLAB. The ice condition of the ice rink is -5.5C (22.1F). A player weighs 50kg and the length of the track (game) is 1000m. The ice rink is 281.07 (m^2). Explain how a player's record changes if the density of ice changes under these conditions. Since the density is mass/volume, the height of the ice is important when the area is known. Therefore, the height changes by 0.5 cm from 0 cm to 5 cm. Plot the player's record (time, s) vs. the density of ice.

Specific question(make the question more concrete) : Pouring water at once to make ice increases oxygen and the strength of the ice weakness. Therefore, a lamination method of freezing water in several layers is used. -- How does the player's record change depending on the density of the ice(higher or lower than 4cm thick -- change volume)?
