High School

Two ice skaters, with masses of 71 kg and 55 kg, stand facing each other on a 17-meter wide frozen river. The skaters push off against each other, glide backward straight toward the river's edges, and reach the edges at exactly the same time.

What is the total mass of the ice skaters?

A. 71 kg
B. 55 kg
C. 126 kg
D. 126 N

Answer :

Final answer:

The total mass of the two ice skaters is the sum of their individual masses, which equals 126 kg.

Explanation:

The total mass of the ice skaters is found by simply adding their individual masses together. Given that one skater has a mass of 71 kg and the other has a mass of 55 kg, the total mass would be:

  • 71 kg + 55 kg = 126 kg.

The other provided options such as 126 N are incorrect, as the unit N (Newtons) is a unit of force, not mass. Since the question asks specifically for mass, the correct answer must be in kilograms (kg).

Therefore, the correct answer to the question, "What is the total mass of the ice skaters?" is 126 kg, which corresponds to option 3.
