3. calculate the given equation (show the solution)1.) a=?vf=81m/svi=9m/st=8s2.)a=? vf=10m/svi=30 m/st=5s3.)a=? vf=250m/svi=50m/st=25s4.)a=? vf=90km/hvi=30km/ht=10h5.)a=? vf=36km/hvi=72km/ht=6h
Explanation:
To solve these problems, we can use the following kinematic equation, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time:
vf = vi + at
We can rearrange this equation to solve for acceleration:
a = (vf - vi) / t
Substituting the given values into this equation, we can find the acceleration in each case:
1. a = (81 m/s - 9 m/s) / 8 s = 9.75 m/s^2
Therefore, the acceleration is 9.75 m/s^2.
2.a = (10 m/s - 30 m/s) / 5 s = -4 m/s^2
Note that the negative sign indicates that the acceleration is in the opposite direction of the initial velocity.
Therefore, the acceleration is 4 m/s^2.
3.a = (250 m/s - 50 m/s) / 25 s = 8 m/s^2
Therefore, the acceleration is 8 m/s^2.
We need to convert the velocities from km/h to m/s, since the unit of time is in hours.
vf = (90 km/h)(1000 m/km)(1 h/3600 s) = 25 m/s
vi = (30 km/h)(1000 m/km)(1 h/3600 s) = 8.33 m/s
4.a = (25 m/s - 8.33 m/s) / (10 h)(3600 s/h) = 0.005 m/s^2
Therefore, the acceleration is 0.005 m/s^2.
We need to convert the velocities from km/h to m/s.
vf = (36 km/h)(1000 m/km)(1 h/3600 s) = 10 m/s
vi = (72 km/h)(1000 m/km)(1 h/3600 s) = 20 m/s
5.a = (10 m/s - 20 m/s) / (6 h)(3600 s/h) = -0.0014 m/s^2
Therefore, the acceleration is 0.0014 m/s^2, with a negative sign indicating that the acceleration is in the opposite direction of the initial velocity.

5. a=?Vf=120m/sVi=60m/st=60s
Answer:
To solve for a, we can use the following equation:
Vf = Vi + at
where Vf is final velocity, Vi is initial velocity, a is acceleration, and t is time.
First, we can rearrange the equation to solve for a:
a = (Vf - Vi) / t
Substituting the given values:
a = (120 m/s - 60 m/s) / 60 s
a = 1 m/s^2
Therefore, the acceleration is 1 m/s^2.
Answer:
a=1 m/s^2.
Step-by-step explanation:
We can use the following kinematic equation to solve for the acceleration (a):
Vf = Vi + at
where:
Vf is the final velocityVi is the initial velocitya is the accelerationt is the time elapsedWe have:
Vf = 120 m/s
Vi = 60 m/s
t = 60 s
Substituting these values into the equation, we get: 120 m/s = 60 m/s + a(60 s)
Simplifying:
60 m/s = 60 s × a
a = (60 m/s) / (60 s)
a = 1 m/s^2
Therefore, the acceleration (a) equals 1 m/s^2.
6. Which of the following formula is used to solve acceleration?a. a= vi-vfltC. a= t-vfl vib. a= vf-vitd. ar viv-t

Answer:
d = 28.6 m
Explanation:
vi = 22.4 m/s
vf = 0 m/s

d = 0/.15
d = (vi + vf)/2 t
d = (22.4 m/s + 0 m/s)/2 2.55 s

20. GivenVi =5 m/s Vf=10m/s t=2.0sGivenVf=15m/sVi=0m/st=3.0s
Answer:
You have two sets of initial and final velocity (Vi and Vf) and time (t) values.
The first set is:
Vi = 5 m/s
Vf = 10 m/s
t = 2.0 s
The second set is:
Vi = 0 m/s
Vf = 15 m/s
t = 3.0 s
These values can be used to calculate the acceleration using the formula:
a = (Vf - Vi) / t
For the first set of values, the acceleration can be calculated as:
a = (10 m/s - 5 m/s) / 2.0 s = 2.5 m/s^2
For the second set of values, the acceleration can be calculated as:
a = (15 m/s - 0 m/s) / 3.0 s = 5 m/s^2
These calculations show that the first set of values has an acceleration of 2.5 m/s^2 and the second set of values has an acceleration of 5 m/s^2.
21. the equation for final speed, vf , where the initial speed was Vo, the acceleration was A , and the time was t is Vf - Vo = AT solve for acceleration? please answer immediately
Deriving acceleration from the formula of final velocity.
Vf = Vi + at
at = Vf - Vi
at / t = Vf - Vi / t
a = Vf - Vi / t

24. VF=Vi+at 20m/s = 5m/s+2(10s)
Answer:
The equation VF = Vi + at represents the final velocity (VF) of an object given its initial velocity (Vi), acceleration (a), and time (t).
To use this equation to solve the given problem, we can simply substitute the given values:
VF = Vi + at
where VF = 20 m/s (final velocity)
Vi = 5 m/s (initial velocity)
a = 10 m/s^2 (acceleration)
t = 2 s (time)
Plugging in these values, we get:
20 m/s = 5 m/s + 10 m/s^2 x 2 s
Simplifying the right side of the equation:
20 m/s = 5 m/s + 20 m/s
Adding like terms:
20 m/s = 25 m/s
This is not a valid solution since the final velocity cannot be less than the initial velocity if the acceleration is positive.
Therefore, we need to recheck the given values and ensure they are correct or if there was a mistake in the equation set-up
Answer:
This solution is wrong
Explanation:
VF=Vi+at
20m/s = 5m/s+2(10s)
20m/s = 5m/s+2(10s)
20m/s = 25m/s
The answer is invalid meaning the solution is wrong because firstly, if you are going this formula, the acceleration must have 9.8 and if there is velocity final, there should be no velocity initial and vice versa.
