Answer:

Total momentum is 17 kg m/s.

Step-by-step explanation:

M1 = 1 kg, m2 = 2 kg, when moving in the same direction with speeds v1 = 5 m/s and v2 = 6 m/s, the momentum of the two bodies is equal to

The momentum is defined as the product of mass and the velocity of body.

Momentum of first body. p' = M1 v1 = 1 x 5 = 5 kg m/s

Momentum of second body, p'' = M2 v2 = 2 x 6 = 12 kg m/s

As they both are moving in the same direction so the net momentum is

p = p' + p''

p = 5 + 12 = 17 kg m/s
