Answer:
0.0135814 kg.m/s
kg.m/s
Step-by-step explanation: When an object with mass is in motion, we say the object has momentum (p). Momentum is dependent on mass and velocity:
p = m.v
The total momentum of Bryce's mice is calculated as
x-axis

![p_(x)=[(0.0213)(0.675)+(0.0165)(-0.249)+(0.0185)(0.395)+(0.0193)(-0.207)]](https://img.qammunity.org/2022/formulas/physics/college/ad7ovlsotr03rqsi36wc9f337x30s1ve6t.png)
0.0135814
At the x-axis, total momentum of Bryce's mice is 0.0135814 kg.m/s.
y-axis

![p_(y)=[(0.0213)(-0.417)+(0.0165)(-0.809)+(0.0185)(0.953)+(0.0193)(0.227)]](https://img.qammunity.org/2022/formulas/physics/college/zsswdeb31yflhpx2jvhoi3zqgway47sobm.png)

At the y-axis, total momentum of Bryce's mice is -0.000219 kg.m/s.
