no picture??

anonymous · Answer

no its just a word problem and asks to draw a vector diagram

anonymous · Answer

you gotta come up with any idea?

anonymous · Answer

well... momentum : p = mv
 and second note is built into this equation; momentum is a vector, and the momentum has the same direction as the velocity.>
"isolated" means that no external force acts on the system, which is a set of interacting objects
 and 
 a elastic - kinetic energy is conserved
inelastic - kinetic energy is not conserved
completely inelastic - kinetic energy is not conserved, and the colliding objects stick together after the collision.

Sorry if i am confusing you

speed is a scalar quantity.  it does not imply direction.

so it makes sense to say that the  2 cars are travelling in opposite directions at the same speed.

momentum is mass times velovity and it is a vector.  if 2 cars are travelling in opposite directions at the same speed, one has momentum mv and the other has momemntum -mv.

you vector diagram is no more than a drawing with arrows pointing in different directions
