a 2.00kg cart travelling north at 4.00m/s collides head on with a 1.00kg cart travelling south at 8.00m/s. what is the magnitude of the total momentum of the two carts after the collision

16 kgm/s

Explanation:

Step one:

given data

m1= 2kg

v1= 4 m/s

m2= 1kg

v2= 8m/s

Required

The magnitude of momentum after impact pafter

Momentum is the product of a moving object's mass and velocity

Step two:

Pa= m1v1+m2v2

Pa=2*4+1*8

Pa=8+8

Pa=16 kgm/s

When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.
