Question

In an inelastic collision between two objects the momentum of each object is conserved. the kinetic energy of each object is conserved. the momentum of the system K conserved but the kinetic energy of the system is not conserved. both the momentum and the kinetic energy of the system are conserved. the kinetic energy of the system is conserved, but the momentum of the system in not conserved. You're working in mission control for an interplanetary space probe. A trajectory correction calls for a rocket firing that imparts an impulse of 5.56 N s. It the rocket s average thrust is 118 mN. how long should the rocket fire?47ms 21s 6.8s 47s A basketball is dropped from the roof of a building. As it falls to the ground below how does its momentum change? it decreases

Explanation / Answer

Ques 6. Option (C) is correct.In an inelastic collision between two objects the momentum of the system is conserved but KE of the system is not conserved.

Ques 7. Option (E) is correct. Impulse is force x time of force appled.
so T=FT / F =5.56/0.118=47.12 seconds.

Ques 8. Option (B) is correct.As basketball falls to the ground below the momentum increases.
