The magnitude of velocity for this car is equal to 1.5 m/s.
<u>Given the following data:</u>
- Momentum of car = 3,000 kgm/s.
To calculate the magnitude of velocity for this car:
<h3>What is momentum?</h3>
In Science, momentum simply means a multiplication of the mass of an object and its velocity.
Mathematically, momentum is giving by the formula;
Making velocity the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Velocity = 1.5 m/s.

The correct answer would be C. Unaware because it is the opposite of leery
This is a trick question:
The Doppler effect states that as you move closer to the source, the frequency of light(or sound/waves in general) increases, but technically the speed of light is always the same speed, even if you are moving at the speed of light.
Thus, the answer would be something along the lines of <u>don't change</u>.
• 3 laps of 200 meter track = 600 meters
• 600 meters ran in 2 minutes
• 2 minutes = 120 seconds
• 600 meters / 120 seconds = 5 m/s on average
Answer:
The answer to the question is A.
Explanation:
The definition of moment is Force multiplied the distance to the point of interest.
So the external moment at point O is equal to ⇒ EMо= F×d
Knowing the definition of moment of inercia (I) and a newtonian Force ( m.a)
We can say that te moment of the externals force at point O is EMо= IGa
Because the rotation of a body in a inmovil point is implicated by the moment of inercia an the action of the gravity in that moment.
