before colliding, the momentum of block a is +25.0 kg*m/s, and block b is +35.0 kg*m/s. after, block a has a momentum +60.0 kg*m/s. what is the momentum of block b afterwards?
(unit = kg*m/s)

0kgm/s

Explanation:

Momentum before collision=momentum after collision

Since the momentum of the two blocks have positive sign, it means they are moving in thesame direction

Therefore we use the formula

Momentum (A)+momentum (B)=Momentum (A)+momentum (B)

25+35=60+momentum (B)

60=60+momentum (B)

Momentum (B)=60-60

Momentum (B)=0kgm/s

i'm thinking more like energy

c) up is the direction the magnetic force is acting on the charge.
