The momentum should be .5 because you multiply the mass and velocity to get momentum

Momentum
<h2>
Explanation:
</h2>
The momentum of a particle is defined as the product of the particle mass and the particle velocity as follows:
On the other hand, the impulse of a constant force is defined as:
We also know that the net force acting on a particle equals the rate of change of the particle’s momentum, so:
If the force is constant, then 
equals the total change in momentum over a period of time:
Answer:
D) They most likely died from not wearing a seatbelt.
Explanation:
Their death was caused by a "motor vehicle" (that's what MV stands for in this case). The most logical answer would be D.
The molecules of a solid vibrate faster so that they spread out to become a liquid hope this helps
Blu ! The formula is right THERE, IN the question. All you have to do is plug numbers into it.
The formula: Kinetic Energy = 1/2 m v²
' m ' is 2,000 kg
' v ' is 22 m/s
Now pluggum in:
KE = (1/2) (2,000 kg) (22 m/s)²
KE = (1/2) (2,000 kg) (22 m/s x 22 m/s)
KE = (1/2) (2,000 kg) (484 m²/s²)
I'm <u><em>sure</em></u> you can finish it off from this point, and pick the correct choice.
