If the initial velocity was zero then final velocity V = 2*S / t
where S = distance covered
and t = time it took
Acceleration a = 2*S / t2
or
a = (V - V0) / t
where (V - V0) is change in velocity.

How do I rearrange the acceleration formula to solve it for initial velocity?
Where a = (v-u)/t a is acceleration, v is final velocity u is initial velocity t is time so, u=v-at
How do you find acceleration when given time and change of distance and velocity?
vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a.vf = vi + at, where t is time time. Solve for a.
What is the equation to solve for average acceleration?
AnswerAcceleration = v2 - v1.........................timeAverage Acceleration requires you to average the the initial velocity of your trials and the ending velocity of your trials. You must also find the average for your time trials. Once you achieve these numbers, just plug them into the above formula and you can solve for average acceleration.
An airplane originally at rest on a runway accelerates uniformly at 6 meters per second for 12 seconds During this 12-second interval the airplane travels a distance of approximately?
The formula for distance covered during uniform acceleration isd = 1/2 * (vf + vi) * t (1)Time, t, is given; initial velocity, vi, is 0; but final velocity, vf, is unknown and must be computed from given information. Knowing the rate of acceleration, initial velocity and time, The final velocity may be computed using the formula for average acceleration (actual acceleration under uniform motion) which isa = (vf - vi) / t (2)Rewriting to solve for vf with vi = 0 we havevf = a * tvf = 6m/s2 * 12svf = 72m/sPlugging this value into equation (1) with the other given values we haved = 1/2 * (72m/s + 0 m/s) * 12sd = 432mSo the airplane will travel 432m from rest in 12 seconds under 6m/s uniform acceleration.
How do you find the time from acceleration and distance?
You can use the formula for distance covered:distance = (initial velocity) x (time) + (1/2) (acceleration) (time squared) Solve for time. This assumes constant acceleration, by the way. If you assume that the initial velocity is zero, then you can omit the first term on the right. This makes the equation especially easy to solve.

Where a = (v-u)/t a is acceleration, v is final velocity u is initial velocity t is time so, u=v-at
How do you solve acceleration in 8th grade?
To solve for acceleration in 8th grade, you can use the formula: acceleration = (final velocity - initial velocity) / time. Remember to ensure that the units for velocity are consistent (m/s or km/h) and time is in seconds. Plug in the values you have to calculate the acceleration.
What to do if the car change its velocity and the given is the acceleration?
If the acceleration of the car is given, you can calculate the change in velocity using the formula: final velocity = initial velocity + (acceleration * time). You need to know the initial velocity and the time for which the acceleration is acting to determine the final velocity.
How do you calculate initial velocity when given final velocity acceleration and time?
You can use the equation: (v_i = v_f - a * t), where (v_i) is the initial velocity, (v_f) is the final velocity, (a) is the acceleration, and (t) is the time. Plug in the values and solve for (v_i).
How do you find the initial velocity just with the accelaration final velocity and time?
You can use the equation: final velocity = initial velocity + acceleration * time. Rearrange the equation to solve for initial velocity: initial velocity = final velocity - acceleration * time. Simply substitute the given values for final velocity, acceleration, and time into the equation to find the initial velocity.
How do you find acceleration when given time and change of distance and velocity?
vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a.vf = vi + at, where t is time time. Solve for a.
How do you get the time without final velocity?
To find the time without knowing the final velocity, you need information about the initial velocity, acceleration, and displacement. You can use the kinematic equation: displacement = (initial velocity * time) + (0.5 * acceleration * time^2) to solve for time.
What is the formula for aceleration?
The first answer is backward. Acceleration = (final velocity - initial velocity)/total time. For deceleration the formula is the same, the answer will just be negative.Agreed. In physics, there is no "deceleration", only negative acceleration.a = Δv / ΔtThere is no equation for "deceleration" as suggested below.Deceleration=(original velocity-final velocity)/TimeDeceleration In MotionDeceleration = inital speed - final speed / total time taken
How do you rearrange the timeless equation for acceleration?
To rearrange the equation for acceleration, you start with the equation (a = \frac{v_f - v_i}{t}) where (a) is acceleration, (v_f) is final velocity, (v_i) is initial velocity, and (t) is time. You can rearrange it to solve for any of the variables by manipulating the equation algebraically. For example, to solve for final velocity, you rearrange the equation as (v_f = v_i + a \times t).
The box decelerates at a rate of 3 m s and skids 24 meters before coming to a stop How fast were you traveling when the box fell out?
To find the initial velocity of the box when it fell out, you can use the formula: final velocity squared = initial velocity squared + 2 * acceleration * distance. Given that the final velocity is 0 m/s, acceleration is 3 m/s^2, and distance is 24 meters, you can solve for the initial velocity.
What is the equation to solve for average acceleration?
AnswerAcceleration = v2 - v1.........................timeAverage Acceleration requires you to average the the initial velocity of your trials and the ending velocity of your trials. You must also find the average for your time trials. Once you achieve these numbers, just plug them into the above formula and you can solve for average acceleration.
A soccer ball is rolling down a field At t0 the ball has in velocity of 4 ms If the acceleration of the ball is constant at -0.3 mss how long will it take the ball 2 come to a complete stop?
To calculate the time it takes for the soccer ball to come to a complete stop, you can use the formula: final velocity = initial velocity + (acceleration x time). In this case, the final velocity is 0 m/s (since the ball comes to a stop), the initial velocity is 4 m/s, and the acceleration is -0.3 m/s^2. Rearranging the formula to solve for time, you would get: time = (final velocity - initial velocity) / acceleration. Plugging in the values, you would get: time = (0 - 4) / -0.3 = 13.33 seconds. So, it will take approximately 13.33 seconds for the ball to come to a complete stop.
