Determine the change in impulse of a 4kg body moving at a speed of 2m / s until it stops.
| March 28, 2021 | education
The change in the momentum of a given body can be calculated using the formula:
ΔР = mV – mV0.
Since the body will stop (V = 0), the formula will take the form:
ΔР = – mV0, where m is the mass of a given body (m = 4 kg), V0 is the initial velocity of the body’s movement (V = 2 m / s).
Let’s perform the calculation:
ΔР = -4 * 2 = -8 kg * m / s.
Answer: The momentum of a given body has decreased by 8 kg * m / s.
