1u. It the momentum oft an objectis 20 kg-m's andits velocity is ɔ m's downward, wnatis the mass of an object? c. 20kg b. 5 kg 11. What is the unit of velocity? b. m/s a. 4 kg d. 25 kg a. kilogram c. Newton d. second 12. An egg was thrown to the wall and to the bedsheet at the same speed and force. Why is it that the egg hasmore damaged whenyou hit the wall thanin the bed sheet? a. because the egg experienced more impact on the wall thanin the bed sheet. b. because the bedsheet is softer than the wall c. because the wall is solid and compacted. d. because the bed sheet absorbed the egg andthe egg stayed onit.
