What is the change in momentum of a body weighing 2 kg, the speed of which has increased from 3 m / s to 5 m / s?
| February 13, 2021 | education
Initial data: m (body weight) = 2 kg; V1 (initial body speed) = 3 m / s; V2 (final speed of body movement) = 5 m / s.
The change in the momentum of a given body can be calculated using the formula: ΔP = P2 – P1 = m * V2 – m * V2 = m * (V2 – V1).
Let’s make calculations: ΔP = 2 * (5 – 3) = 4 kg * m / s.
Answer: The change in momentum of the body will be 4 kg * m / s.
