Question

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

Answer 1

16 kgm/s

Step-by-step 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
