A=Vf - Vi divided by 29 seconds
Can you please help me. This is 9th grade Physical Science homework.
Of course! I'd be happy to help you with this equation from your Physical Science homework.
The equation you provided is used to calculate acceleration (A) given the final velocity (Vf), initial velocity (Vi), and time (29 seconds). To solve this equation, you'll need to know the values for Vf, Vi, and 29 seconds.
To find the value of A, you'll need to subtract the initial velocity (Vi) from the final velocity (Vf), and then divide that difference by 29 seconds. Here's the step-by-step process:
1. Identify the values for Vf, Vi, and 29 seconds. Make sure you know the units they are given in (e.g., meters per second, kilometers per hour, etc.).
2. Subtract the initial velocity (Vi) from the final velocity (Vf). This will give you the difference between the two velocities.
3. Divide the difference between Vf and Vi by 29 seconds. This will give you the acceleration.
Let's go through an example:
If Vf = 50 m/s and Vi = 20 m/s, we can substitute these values into the equation:
A = (Vf - Vi) / 29 seconds
= (50 m/s - 20 m/s) / 29 seconds
Now, subtract the initial velocity from the final velocity:
A = 30 m/s / 29 seconds
Finally, divide the difference by 29 seconds:
A ≈ 1.034 m/s^2
Therefore, the acceleration is approximately 1.034 m/s^2.
Remember to check the units of your answer to make sure they are consistent with the given units in the problem.
