Answer:
775 grams of ice
Explanation:
Heat loss by patient = heat gained by ice
Heat loss by patient = mass×specific heat capacity×(initial temperature - final temperature) = 62×4200×(40-39) = 260,400J
Heat gained by ice = mass × specific latent heat of fusion of ice = m×336000 = 336000m J
336000m = 260,400
m = 260400/336000 = 0.775kg = 0.775×1000 grams = 775 grams of ice
Assuming this roller coaster has zero change in total energy, the cars are descending and speeding up when they gain kinetic energy.
