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.
Answer:
Explanation:
The values of the position and velocity of the ball are missing in the text - found the table in internet, see attached picture.
We can solve this problem by using the following SUVAT equation:
v(t) = u +at
where
v(t) is the velocity of the rock at time t
u is the initial velocity
a is the acceleration of gravity on the planet
t is the time
At t = 0, u = 20 m/s.
After 1 second, t = 1 and v = 15 m/s. Substituting these values and solving for a, we find:
And the negative sign means the acceleration is downward.
The independent variable is usually placed on the x-axis of the graph.
- A graph shows the relation between two quantities in which one quantity is affected by the other
- Generally, a graph has 2 axes x and y, horizontal and vertical respectively
- A variable which is not affected by the other variable is known as the independent variable
- The dependent variable is dependent on the value of the independent variable
- For example, in a graph where we plot the distance versus time, time is the independent variable and the distance is the dependent variable
- The distance covered depends on the time elapsed
- Usually, the horizontal axis is assigned to an independent variable
Therefore, we typically plot the independent variable on the x-axis of a graph.
