Answer:
4.3 m/s
Explanation:
Using conservation of momentum, assume that the collision is elastic and that the 3.0 g ball stuck with the carton
3.0 g = 3 / 1000 = 0.003 kg = m₁
40 g = 40 / 1000 = 0.04 kg = m₂, u₂ = 0 since the body is stationary and v = 0.3m/s
m₁u₁ + m₂u₂ = v ( m₁ + m₂)
0.003 u₁ = 0.30 ( 0.003 + 0.04) = 0.0129
u₁ = 0.0129 / 0.003 = 4.3 m/s

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.
