The momentum after objects collide in a perfectly inelastic collision is written as:

Tags

112.45.c.7.E

The momentum before objects collide is always written as:

Tags

112.45.c.7.E

Conservation of momentum means that the initial and final momentum in a collision are

• different

• the same/equal

• impossible to determine

• always the same as the kinetic energy

The total momentum before a collision is _________ the total momentum after a collision.

• equal to 
• less than 
• more than
• It depends on the type of collision

A projectile of mass 1 kilogram traveling at 9 meters per second collides with another projectile of mass 2 kilograms traveling at 6 meters per second in the same direction. If the projectiles "stick" together after their collision, what is their velocity after colliding?

• 7 m/s

• 8 m/s

• 7.5 m/s

• 9 m/s
