The body mass was increased 2 times, and the body speed decreased 4 times. How did the impulse of the body change?

Initial data: change in body weight: m2 (final weight) = 2m1 (initial weight); change in body speed: V2 (final speed) = 1/4 V1 (initial speed).

1) Initial impulse of the body: P1 = m1 * V1.

2) The final impulse of the body: P2 = m2 * V2 = 2m1 * 1/4 V1 = m1 * V1 / 2.

3) Change in body impulse: P2 / P1 = (m1 * V1 / 2) / (m1 * V1) = 1/2.

Answer: The impulse of the body has decreased by 2 times.
