Q: Spaceship 1 and Spaceship 2 have equal masses of 300 kg Spaceship 1 has a speed of 0 ms and Spaceship 2 has a speed of 4 ms They collide and stick together What is their speed?

Write your answer...

3 m/s

2 m/s

3 m/s

2 m/s*heather :)*

The new speed for the combined masses will be one-half the original velocity of the moving spaceship, since the momentum is applied to a mass twice as large.

2m/s

1800 kg-m/sec 600 kg x 3 meters/sec (in the direction spaceship 2 was headed). Since the first spaceship had all the initial momentum, only the velocity of the combined mass will change.

900kg?

It is 600 newton.

2,000 kg-m/s "Apex"

600kg-m/s apex miles

momentum must be conserved momentum = mass*velocity initially momentum = 150*6 +150*0 = 900 kgms-1 final momentum = 300*combinedvelocity = 900 so the final velocity must be 3 ms-1

Momentum = (mass) x (velocity), in the same direction as the velocity.Spaceship-1 . . . Momentum = (200) x (0) = 0 kg-m/sec, in some direction.Spaceship-2 . . . Momentum = (200) x (6) = 1200 kg-m/sec, in the same direction.Their combined momentum = 1200 kg-m/sec, in their common direction.

Generally, no.

Momentum = (mass) x (velocity), in the same direction as the velocity.Spaceship-1 . . . Momentum = (150) x (0) = 0 kg-m/sec, in some direction.Spaceship-2 . . . Momentum = (150) x (6) = 900 kg-m/sec, in the same direction.Their combined momentum = 900 kg-m/sec, in their common direction.

6 m/s 30 m/s

2 m/s :)

30 m/s - Apex

Multiply mass x velocity for each spaceship. Add the results.

1,800 kg-m/s

2,000 kg-m/s
