Question

Spaceship 1 and Spaceship 2 have equal masses of 200 kg. They collide.

Spaceship 1's final speed is 2 m/s, and Spaceship 2's final speed is 1 m/s in
the same direction. What is their combined momentum?

O
B. 400 kg-m/s
C. 800 kg-m/s
D. 600 kg-m/s

Answer 1

The Answer is 600 kg-m/s

Answer 2

Answer: 600 kg-m/s

Step-by-step explanation:

Momentum = mass x velocity

momentum of spaceship 1 = 200 x 2

= 400 kg-m/s

momentum of spaceship 2 = 200 x 2

= 200 kg-m/s

Their combine momentum = 400 + 200 = 600 kg-m/s
