I = V / R = 9v / 36ohms = 1/4 Ampere
Given:
Momentum of the dog (p) = 120.5 kg m/s
Speed of the dog (v) = 5 m/s
To Find:
Mass of the dog (m)
Concept/Theory:

- It is defined as the quantity of motion contained in a body.
- It is measured as the product of mass of the body and it's speed.
- It is represented by p.
- It's SI unit is kg m/s
- Mathematical Representation/Equation of Momentum:

Answer:
By using equation of momentum, we get:

Mass of the dog (m) = 24.1 kg
Answer:
4N downward
Explanation:
the 16N left and right cancel each other out, so you are left with the 4N downward.
Recall that

where
is the luger's initial velocity,
his final velocity,
his acceleration, and
the distance he traverses. Then


so the closest answer is C.
