A stone is dropped from a height h. It hits the ground with a certain momentum P. If the same stone is dropped from a height 100% more than the previous height, the momentum when it hits the ground will change by

Question

Dr. Abubacker · Accepted Answer

[Solution from source] Momentum on hitting the ground is P = m√(2gh). Doubling the height multiplies P by √2 ≈ 1.414, an increase of about 41%. Doubling the momentum (100%) would need four times the height. Answer (2).
