A baby ball weighing 100 g falls from the roof of a high-rise building. Find its impulse 1.5 s after the start of the fall.

Initial data: m (weight of a baby ball) = 100 g (0.1 kg); t (time elapsed after the ball started falling) = 1.5 s; the fall of the child’s ball will be considered free (V0 = 0 m / s).

Reference data: g (acceleration due to gravity) ≈ 10 m / s2.

1) Determine the speed of the children’s ball in 1.5 s: V = V0 + a * t = g * t = 10 * 1.5 = 15 m / s.

2) Let’s calculate the impulse: P = m * V = 0.1 * 15 = 1.5 kg * m / s.

Answer: The impulse of the baby ball will be 1.5 kg * m / s.
