Car 1 is parked when it is hit by Car 2. The momentum of Car 2 before the collision was 50 kg m/s. The momentum of Car 1 after the collision is 10 kg m/s. What is the momentum of Car 2 AFTER the collision?
40 kg m/s
conserve momentum:
0 + 50 = 10 + p
To find the momentum of Car 2 after the collision, we need to use the principle of conservation of momentum. According to this principle, the total momentum before the collision is equal to the total momentum after the collision.
Before the collision, the momentum of Car 2 was 50 kg m/s.
After the collision, the momentum of Car 1 is 10 kg m/s.
Since the total momentum before and after the collision must be the same, we can subtract the momentum of Car 1 after the collision from the initial momentum of Car 2 to find the momentum of Car 2 after the collision.
Momentum of Car 2 after the collision = Initial momentum of Car 2 - Momentum of Car 1 after the collision
Momentum of Car 2 after collision = 50 kg m/s - 10 kg m/s
Momentum of Car 2 after the collision = 40 kg m/s
To find the momentum of Car 2 after the collision, we can use the law of conservation of momentum. According to this law, the total momentum before the collision is equal to the total momentum after the collision.
The momentum of Car 1 before the collision is zero, as it is parked and not moving. Therefore, the total momentum before the collision is equal to the momentum of Car 2 before the collision.
So, the momentum of Car 2 after the collision can be calculated using the equation:
Momentum before collision = Momentum after collision
Car 2 momentum before collision = Car 2 momentum after collision
Therefore, the momentum of Car 2 after the collision is also 50 kg m/s.
