Question

Spaceships 1 and spaceships 2 have equal masses of 200kg. They collide. Spaceship 1’s final speed is 2 m/s and spaceships 2’s final speed is 1 m/s in the same direction. What is their combined momentum

Answer 1

600 kg*m/s.

Step-by-step explanation:

To determine the combined momentum of spaceships 1 and 2 after the collision, we need to use the formula for momentum, which is given by:

p = mv

where p is momentum, m is mass, and v is velocity.

We know that the masses of both spaceships are equal to 200 kg, and that the final velocities of spaceship 1 and spaceship 2 are 2 m/s and 1 m/s, respectively. Therefore, the momenta of spaceship 1 and spaceship 2 after the collision are:

p1 = m1v1 = 200 kg * 2 m/s = 400 kgm/s

p2 = m2v2 = 200 kg * 1 m/s = 200 kgm/s

To find the combined momentum, we can simply add the momenta of the two spaceships:

p1 + p2 = 400 kgm/s + 200 kgm/s

= 600 kg*m/s

Therefore, the combined momentum of spaceships 1 and 2 after the collision is 600 kg*m/s.
