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:

$\vec p = p_x\mathbf{i}+p_y\mathbf{j}$

The magnitude of the momentum is:

$\mid \mid \vec p \mid \mid =√(p_x^2+p_y^2)$

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:

$\mid \mid \vec p \mid \mid =√(8.5^2+9.8^2)$

$\mid \mid \vec p \mid \mid =√(72.25+96.04)$

$\mid \mid \vec p \mid \mid =√(168.29)$

$\mid \mid \vec p \mid \mid =12.97$

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