Answer:
Total momentum, p = 21.24 kg-m/s
Explanation:
Given that,
Mass of first piece,
Mass of the second piece,
Speed of the first piece, (along x axis)
Speed of the second piece, (along y axis)
To find,
The total momentum of the two pieces.
Solve,
The total momentum of two pieces is equal to the sum of momentum along x axis and along y axis.
The net momentum is given by :
p = 21.24 kg-m/s
Therefore, the total momentum of the two pieces is 21.24 kg-m/s.
