Explanation Write the expression for momentum of the baseball. p → = m v → (I) Here, p → is the momentum of the ball, m is the mass, v → is the velocity. Write the expression for momentum vector. p → = | p → | 〈 sin θ , cos θ , 0 〉 (II) Write the expression for the change in momentum. Δ p = p f − p i (III) Conclusion: Substitute, 50 kg for m , and 5 m / s for v → , in equation (I) to find the momentum. p → = 50 kg × 5 m / s = 250 kg ⋅ m / s Substitute, 0 ° for θ , and 250 kg ⋅ m / s for p → in equation (II) to find the initial momentum of the child. p → i n = 250 kg ⋅ m / s 〈 sin 0 , cos 0 , 0 〉 = 〈 0 , 250 , 0 〉 kg ⋅ m / s Substitute, 360 ° for θ , and 250 kg ⋅ m / s for p → in equation (II) to find the final momentum of the child
