To solve the equation vf = vi + at, where vf is the final velocity, vi is the initial velocity, a is the acceleration, and t is the time, you first need to identify the values of vi, a, and t. Then, substitute these values into the equation and solve for vf by adding vi and the product of a and t. This equation is derived from the kinematic equation vf = vi + at, which relates the final velocity of an object to its initial velocity, acceleration, and time.

A ball is thrown straight up with an initial speed of 40 ms How high does it go?
The ball reaches a maximum height of ~81.6 meters. How to do it: Find the change in time using Vf = Vi -g(t) We know: Vf = 0 (terminal velocity) and Vi = 40 (given in question) So, Vf = Vi - g(t) => 0 = 40 - g(t) --Rework the equation to solve for t... t = 40/g => since g = 9.8... t = 40/9.8 ~ 4.08 So the change in time is about 4.08 seconds Now plug your new values into the kinematics equation Yf = Yi + Vi(t) + 1/2(a)(t^2) Plug in our values and solve => Yf = 0 + (40 * 4.08) - (9.8 * 4.08^2)/2 Therefore, Yf = 81.6 meters. This is your maximum height. Remember to find the time taken for the ball to fall from this height back to the ground if you need to calculate the total time of the fall.

How do you calculate beginning speed of an object?
The beginning speed of an object can be calculated using the equation: Vf = Vi + at where: Vf = final speed Vi = initial speed a = acceleration t = time You can rearrange the equation to solve for Vi: Vi = Vf - at
What is vi equals vf-at?
Yes recalling the first equation of motion ie Vf = Vi + at Here Vf is final velocity and Vi is the initial velocity. a the acceleration and t is the time Now taking at on the other side ie left side we get Vf - at = Vi This is what mentioned here.
What is the correct formula manipulation to find acceleration when using the equation vf2 vi2 2ad?
To find acceleration using the equation vf^2 = vi^2 + 2ad, you can rearrange the formula to isolate 'a'. First, subtract vi^2 from both sides to get vf^2 - vi^2 = 2ad. Then, divide both sides by 2d to solve for acceleration: a = (vf^2 - vi^2) / (2d).
What is an equation in physics?
f=ma vf=vi+at s=vi+1/2at
What is the linear acceleration equation and how is it used to calculate the acceleration of an object moving in a straight line?
The linear acceleration equation is a (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time. This equation is used to calculate the acceleration of an object moving in a straight line by finding the change in velocity over time.
An arrow shot straight up into the air reached height of 75m with what velocity did it leave the bw how long was the arrow in the air?
To find the initial velocity of the arrow, you can use the equation Vf^2 = Vi^2 + 2gh, where Vf is the final velocity (0 m/s at the top of the flight), Vi is the initial velocity, g is the acceleration due to gravity, and h is the height reached (75m). Solve for Vi to get the initial velocity. To find the time the arrow was in the air, you can use the equation h = Vit - 0.5g*t^2, where t is the time in the air. Plug in the known values to solve for t.
What is the formula for a change in velocity?
Two ways: If the change in velocity is the result of hitting something, use the Momentum Equation. If the change in velocity is the result of applying a force, use the Impulse Equation. You probably mean this equation, which is: FT = m(Vf - Vo) Or, An object of mass "m" will change from velocity "Vo" to velocity "Vf" if the force "F" is applied for "T" seconds.
What is the equation for average acceleration?
A equals Vf minus Vi divided by time equals triangle v divided by time
How do you find initial velocity without time?
Well this could be a one step or 2 step question D= (vi + vf)/2 x t an solve for time or...2 step v^2= vi^2 + 2ad: once you have found a, use: V=vi + at then solve for time
What is the equation for linear acceleration and how is it used to calculate the rate of change in velocity of an object?
The equation for linear acceleration is a (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time. This equation is used to calculate the rate of change in velocity of an object by finding the difference between the final and initial velocities, and dividing that by the time taken for the change to occur.
How do you find the initial velocity just with the accelaration final velocity and time?
To find acceleration, you take Vi [Initial Velocity] and you subtract if from Vf [Final Velocity.] (Vi - Vf) If they Vi and Vf are already given, you take the two givens and you subtract them from each other. Vi minus Vf. Do not do Vf minus Vi or it will be wrong. After you do that, you divide your answer from T [Time] (Vi - Vf) a= _____ t Once you get your answer, that will be your acceleration.
In the acceleration equation a vf - vi t vi represents?
In the acceleration equation, the term vi represents the initial velocity, which is the velocity of an object at the beginning of the time period being considered. This term is subtracted from the final velocity (vf) to determine the change in velocity over time (t), which is then used to calculate the acceleration of the object.
