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.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6
