Answer:
The resultant momentum is 12.97 kg.m/s. Choice: c
Step-by-step explanation:
Momentum
The momentum is a vector that measures the quantity of motion that an object has. It's also known by the term "mass in motion".
As a vector, it can be expressed by its rectangular components:

The magnitude of the momentum is:

The object described has an x-component of:
px=8.5 Kg.m/s
And a y-component of:
py=9.8 Kg.m/s
Thus, the magnitude of the momentum is:




The resultant momentum is 12.97 kg.m/s. Choice: c
