Equal forces or balances forces cancel each other out. One side would have to have more force to move in the direction of least force.
Answer and working shown on photo, final answer for number electrons=2.5*10^17 electrons
Momentum is a protector the mass and the velocity of a moving object.
Momentum= mass*speed
For Car A: Mass:1,000 kilograms Velocity: 40 meters/second;
Momentum=1,000 kg*40 m/s
=40000kg.m/s
For Car B: Mass: 4,000 kilograms Velocity 10 meters/second;
Momentum=4000kg*10m/s
=40000kg.m/s
Both cars require the same amount of force to stop. This is because they have the same momentum.
