The body moves in a straight line. Under the action of a constant force equal in modulus 10N, the body’s momentum in the inertial reference frame changed by 5 kg m / s. How long did it take for this?

To find the duration of the action of the force for the required change in the momentum of a given body, we use the formula: ΔР = F * t, from where we express: t = ΔР / F.

Values of variables: ΔР – pulse change (ΔР = 5 kg * m / s); F – constantly acting force (F = 10 N).

Let’s perform the calculation: t = ΔР / F = 5/10 = 0.5 s.

Answer: It took 0.5 s to change the momentum of a given body.
