The following objects have velocity and mass as given: Object A: m=5 kg, ⃗v=-11 ^j Object B: m=6 kg, ⃗v=5^ i + 8.7 ^ j Object C: m=10 kg, ⃗v=-10 ^i Find the x - and y-components of the net momentum of the system objects if we define the system to consist of (a) objects A and C (b) objects B and C (c) objects A, B, and C

Gerald Fuller · Answer 1

For object A

m = 5 kg, v = - 11 j

For B object

m = 6 kg, v = 5 i + 8.7 j

For object C

m = 10 kg, v = - 10 i

We know that

Linear momentum P = m v kg. m/s

a) A and C

Momentum in y direction

Py = - 5 x 11 j = - 55 j kg. m/s

Momentum in x direction

Px = - 10 x 10 j = - 100 i kg. m/s

b) B and C

Momentum in y direction

Py=6 x 8.7 j = 52.2 j kg. m/s

Momentum in x direction

Px = (6 x 5 - 10 x 10) i = - 70 i kg. m/s

c) A, B and C

By using data of a and b

Momentum in y direction

Py = 6 x 8.7 - 5 x 11 j = - 2.8 j kg. m/s

Momentum in x direction

Px = 6 x 5 - 10 x 10 i = - 70 i kg. m/s
