A bullet weighing 10 g flies at a speed of 410 meters per second, dries up and stops.

A bullet weighing 10 g flies at a speed of 410 meters per second, dries up and stops. Find the change in momentum of the bullet.

Given:
m = 10 g;
V0 = 410 m / s.
Find: change in momentum p.
Decision:
To find the change in momentum, you must use the formula. Let us denote the change in momentum as dp. Let’s write down the formula.
dp = m * V – m * V0.
We take into account that V = 0, then the formula will take the form: dp = m * V0.
Let’s convert the mass into a more convenient system of calculation. Then we get: m = 0.01 kg.
Now we can substitute values into the formula. We get: dp = 0.01 * 410 = 4.1 kg * m / s.
Answer: 4.1 kg * m / s
