Answer:
To become magnetized, another strongly magnetic substance must enter the magnetic field of an existing magnet.
Ptotal=Ptotal —> m1v1+m2v2=m1v1’+m2v2’ —> (1kg)(2m/s)+(1kg)(0m/s)=(1kg)(-1m/s)+(1kg)(v2’) —> v2’=3m/s
answer: v=3m/s
Suppose I wanted to answer this question about the model.
What info about the model would I need to know in order to
make any intelligent guess about the model ?
Hint:
It would really help if I could SEE the model, or at least a photo of it.
