3. A 900 kg car has a velocity of 22.0 m/s. a. Find the momentum (p) of the car.
Given:
m=
V=
Unknown:
P=
Solution:
p = mv

(IT IS NOT A Multiple choice question)

19800kgm/s

Explanation:

Given parameters:

Mass of car  = 900kg

Velocity  = 22m/s

Unknown:

Momentum of the car  = ?

Solution:

The momentum of a body is the quantity of motion it possess.

 So;

        Momentum  = mass x velocity

So;

   Momentum  = 900 x 22  = 19800kgm/s

the answer is 100. i just did this lesson and got a 100% on it. : )

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
