there will be no noise with the ball
The object with the greater mass has a greater gravitational force and that determines what satellites orbit around it. An object with more mass will never orbit an object with less.
Since the rabbit is moving at constant velocity, therefore
the acceleration is zero, hence the increase in distance over time would simply
be:
x = v t
where v is velocity and t is time, x is distance
Since we are starting at x = 8.1 m, the equation of motion
would therefore be:
<span>x = 8.1 – 1.6 t</span>
Um... This is not exactly physics...(Although, this school of thought is most likely Moral Relativism.)
So, the total energy value that has been transferred by work is <u>32 kJ</u>.
<h3>Introduction</h3>
Hi ! In this question, I will help you. <u>Work is the amount of force exerted to cause an object to move a certain distance from its starting point</u>. In physics, the amount of work will be proportional to the increase in force and increase in displacement. Amount of work can be calculated by this equation :
With the following condition :
- W = work (J)
- F = force (N)
- s = shift or displacement (m)
Now, because in this question, the "s" is not directly known, whereas it is known that the initial velocity is zero, the object has an acceleration, and is moving in certain time intervals. Then, use this formula to find the value of "s" !
With the following condition :
- s = shift or displacement (m)
- a = acceleration (m/s²)
- t = interval of the time (s)
<h3>Problem Solving </h3>
We know that :
- a = acceleration = 4 m/s²
- t = interval of the time = 20 s
- m = mass = 10 kg
What was asked :
Step by Step :
- Calculate value of force by multiple m and a
- Calculate value of shift or displacement
- Last, calculate the value of work
So, the total energy value that has been transferred by work is 32 kJ.
