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 6 ms If they collide and stick together what is the combined momentum?

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.


Spaceship 1 and spaceship 2 have equal masses of 300 kg they collide spaceship 1s final speed is 2 ms and spaceship 2s final speed is 1 ms in the same direction what is their combined momentum?

Momentum is mass multiplied by velocity. The momentum of the two ships would be 300 x 2 = 600 kgm/s and 300 x 1 = 300 kgm/s. So the combined momentum of the two ships would be 900 kgm/s.

If two spaceships have equal masses and one is stationary and one is moving What is their combined speed if they collide and stick together?

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.


Spaceship 1 and Spaceship 2 have equal masses of 150 kg Spaceship 1 has a speed of 0 ms and Spaceship 2 has a speed of ms They collide and stick together What is their speed?

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


Why does momentum have a direction?

Momentum is defined as inertia multiplied by velocity. And velocity has a direction. When a object interacts with other objects they collide and change directions.


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?

2 m/sec in the direction of travel of Spaceship 2, assuming they are both in frictionless outer space.


What is momentum in physics?

In physics, momentum = mass x velocityhigher the mass or higher the velocity, higher is the momentum. Note, momentum is a vector quantity i.e it has both magnitude and direction. For instance, when two bodies A of velocity 3m/s and B of velocity 6m/s both of equal masses collide, A moves in the direction of B. Mathematically, the momentum of A is given a negative sign(-) meaning that the momentum of A is in the direction of B


What is the force when to objects collide?

momentum


How is momentum conserved after two object collide?

From Newton's third law, when two bodies A and B collide, the force that A exerts on B is equal in magnitude but opposite in direction to the force that B exerts on A. From Newton's second law, this force produces a rate of change of momentum. Both bodies are experienced to the same magnitude in change of momentum but in opposite directions. Net change in momentum is zero. This implies that momentum is conserved.
