Question

1)A closed system consists of 2 objects. Initially, object A has a momentum of 39 kg·m/s north and object B has a momentum of 74 kg·m/s south. The two objects have a head-on collision. Afterwards, object A is observed to have a momentum of 42 kg·m/s south. After the collision, what is object B's momentum and direction(East,West,North,South,right, left,up, down, or no direction because b has stopped)?

2)A satellite is in orbit about Earth. Its orbital radius is 7.76×107 m. The mass of the satellite is 7944 kg and the mass of Earth is 5.979×1024 kg. Determine the orbital speed of the satellite in mi/s. 1 mi/s = 1609 m/s.

Explanation / Answer

Momentum of A before collision p = 39 j

Momentum of  B before collision p ‘ = 74 (-j)

Momentum of A after collision P = -42 j

From law of conservation of momentum p + p' = P + P'

From this momentum of B after collision P ' = (p+p’ )- P

                                                                        =-7 j

 i.e., in south direction
