7. According to the conservation of momentum, the momentum before a collision should be momentum after a collision. A. twice the object's B. greater than the C. the same as the D. less than the 8. The momentum of a boy running at 12.5 m/s is 600 kg.m/s. What is the mass of the boy? A. 48 kg B. 55 kg C. 75 kg D. 80 kg 9. Jennifer heard the bell ringing signaling the start of the class quickening her pace. If her momentum is changed to 225 kg.m/s and her mass is 48kg, what is her velocity? A. 4.7 m/s B. 5.4 m/s C. 6.3 m/s D. 7.0 m/s 10. Collision is an interaction between two or more bodies that come in contact with each other. Which type of collision is described where bodies separate after the collision and kinetic energy is conserved? C. Non-elastic collision D. Perfectly inelastic collision A. Elastic collision B. Inelastic collision
