Afirecracker breaks up into two pieces, one of which has a mass of 200 g and flies off along the x-axis with a speed of 82.0 m/s. the second piece has a mass of 300 g and flies off along the y-axis with a speed of 45.0 m/s. what is the total momentum of the two pieces?

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.
