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.
Well, let's break it down nice and easy. To solve the equation vf = vi + at, you first subtract vi from both sides to isolate vf. Then, you multiply a by t and add the result to vi to find vf. Remember, take your time and enjoy the process of solving equations like this - it's just like painting a happy little picture!
f=ma vf=vi+at s=vi+1/2at
A equals Vf minus Vi divided by time equals triangle v divided by time
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.
(vf-vi)/ t is ?
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.

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
The equation vi = vf - at relates the initial velocity (vi), final velocity (vf), acceleration (a), and time (t) of an object moving with constant acceleration. This equation is derived from the kinematic equation vf = vi + at using algebraic manipulation.
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).
f=ma vf=vi+at s=vi+1/2at
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.
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.
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
A equals Vf minus Vi divided by time equals triangle v divided by 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.
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.
Change in velocity is found by subtracting the initial velocity from the final velocity. Mathematically, it can be expressed as Ξv = vf - vi, where Ξv is the change in velocity, vf is the final velocity, and vi is the initial velocity.
