These are the troublesome questions.
What is the average velocity between 0.6 h and 1 h?
A. + 0.4 km/h
B. + 1.25 km/h
C. + 1.66 km/h
D. + 2.5 km/h
The other question is below.
What is the object's displacemnt between 0.4 h and 0.6 h?
A. -0.75 km
B. +0.25 km
C. +0.75 km
D. +1.0 km
I work out things the simple way, so I please request you not to post difficult equations and stuff that I won't be able to understand.
I think you must be reading a graph and answering equations about it.
I am also wondering if the "simple" way for you is to ask for answers, and then submit your work. I have never seen you once post your work here.
Sure! I'll explain how to get the answers to these questions in a simple way.
1. Average Velocity:
To find the average velocity, you need to know the formula:
Average Velocity = Total Displacement / Total Time
For the first question, we need to find the average velocity between 0.6 h and 1 h. Since we are dealing with velocity, we need to find the displacement and the time.
Displacement is the change in position, and in this case, we need to find the displacement between 0.6 h and 1 h. It means we need to find the position at those two times and calculate their difference.
Here's how:
- The position at 0.6 h: Let's call it P1.
- The position at 1 h: Let's call it P2.
Once you find the positions at those two times, you can calculate the displacement by subtracting P1 from P2.
Once you have the displacement, you can divide it by the time taken (0.4 h) to find the average velocity.
Now, let's check the answer choices and see which one matches the calculated average velocity.
2. Displacement:
The displacement is the change in position of an object. To find it, we need to know the positions at the starting and ending times.
For the second question, we need to find the displacement between 0.4 h and 0.6 h. The process is similar to finding the average velocity, except that we only need to calculate the displacement, not divide it by the time.
Again, find the positions at both times and subtract the initial position from the final position to get the displacement.
After calculating the displacement, check which answer choice matches the calculated value.
Remember, the key here is to find the difference in positions or displacements between the given times and choose the answer that matches the calculated value.
