Answer:
2000 kg
Explanation:
Given that Which will have a larger momentum when moving at the same speed: a 2,000-kg truck or a 1,000-kg sedan
According to the definition of momentum, momentum is the product of mass and velocity.
That is,
Momentum = mass × velocity
Since velocity or speed is the same, then, the one of higher mass will have a greater momentum.
Therefore, the 2000 kg truck will have the greater momentum.
