The answer is d. I hope that helps.
HI!
Conventional vehicles use gasoline or diesel to power an internal combustion engine. Hybrids also
use an internal combustion engine—and can be fueled like normal
cars—but have an electric motor and battery, and can be partially or
wholly powered by electricity. Also pollute less and save the drivers money.
Good Day.

Don't be there, notice patterns, ask for help.
Explanation:
Answer:
Both vehicles experience the same change in momentum
Explanation:
Let m represent the mass of the vehicle, and 2m represent the mass of the large truck, and let v represent their initial speed, we have;
The total initial momentum, given as follows;
= 2·m·v - m·v = m·v
The total final momentum, = (2·m + m) ×
By the principle of conservation of linear momentum, the total initial momentum = The total final momentum
m·v = (2·m + m) ×
m·v = 3·m·
∴ v = 3 ×
= v/3
The change in the momentum for the large truck = 2·m·v - 2·m·
Therefore;
The change in the momentum for the large truck = 2·m·v - 2·m·v/3 = 2·m·(v - v/3)
The change in the momentum for the large truck = 2·m·(v - v/3) = 2·m·2·v/3 = 4·m·v/3
The change in the momentum for the car = m·v - m·(-) = m·v - m·(-v)/3 = m·v + m·(v)/3 = 4·m·v/3
Therefore, the change in the momentum for the large truck = The change in the momentum for the car and both vehicles experience the same change in momentum.
