The option that accounts for more than half the mass of the asteroid belt is A) Ceres, Vesta, Pallas, Hygiea, and Euphrosyne contain half the mass.
<h3>How to explain the asteroid?</h3>The asteroid belt is roughly between the orbits of Jupiter and Mars. They are also known as minor planets and serve as a source of information about the solar system.
The total mass of the asteroid belt is estimated to be 2.81021 to 3.21021 kilograms, which is only about 4% of the mass of the moon, and Ceres, Vesta, Pallas, Hygiea, and Euphrosyne contain roughly half of this mass (approx 50%).
One thing to note is that ceres is the largest of them all. As a result, option A is the best choice.

Explanation:
It is given that,
The acceleration of the toboggan,
Initial speed of the toboggan, u = 0
We need to find the distance covered by the toboggan. Using the second equation of motion as :
At t = 1 s
At t = 2 s
At t = 3 s
Hence, this is the required solution.
