A 5.00 kg ball is moving at 4.0 m/s to the right and a 6.00 kg ball is moving at 3.00 m/s to the left. The total momentum of the system is

38Kgm/s

Explanation:

Momentum (p) = mass (m) × velocity (v)

Total momentum is the sum of all the momenta of each object in a system. That is:

Total momentum = {m1v1} + {m2v2}

Where;

m1 = mass of ball 1 = 5kg

v1 = velocity of ball 1 = 4m/s

m2 = mass of ball 2 = 6kg

v2 = velocity of ball 2 = 3m/s

Total momentum = {5 × 4} + {6 × 3}

Total momentum = {20} + {18}

Total momentum = 38Kgm/s

the answer is b

explanation:

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
