If the speed is 7 meters per second all the time, then you already have your initial and final speed. If the speed changes, you need additional information.

Formula for finding time?
if acceleration a, initial velocity vi and final velocity vf is given , then time could be found by applying formula t=vf-vi/aand if distance s and velocity v is given then t=s/v
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 find acceleration if only given a velocity?
If you have an initial and final velocity and time you can figure it out with this equation, Vf squared=Vi squared1/2a(t squared) If you don't have those you cannot find acceleration. However the acceleration on Earth is a constant -9.81
Formula for velocity?
V = d / t (or v = dd/dt & v = integral of acceleration with respect to time for physics involving calculus) where V is velocity, d is displacement (distance traveled) and t is time. vf = vi + a*t (vf)^2 = (vi)^2 + 2*a*d Where vf is final velocity, vi is initial velocity, and a is acceleration v = p/m Where p is object's momentum and m is object's mass
What is the formula of vertical velocity?
vf=vi+at or vf2=vi2+2ad where a=-9.8m/s2
What is the formula to find accelerate?
To find acceleration, it is the change in velocity over the change in time. (Vf-Vi)/t. where: Vf is final velocity, Vi is initial velocity, and t is the time interval.

How do you find change in velocity?
Change in velocity is found by subtracting the initial velocity from the final velocity. Mathematically, it can be expressed as Δv = vf - vi, where Δv is the change in velocity, vf is the final velocity, and vi is the initial velocity.
A rocket ship leaves the earths atmosphere its initial velocity is less than its final velocity this is example of?
Final velocity vf is greater than the initial velocity vi . That is vf > vi . This is an example of acceleration (positive). Average acceleration aav = [vf - vi]/[tf - ti] where ti is initial time, and tf is final time.
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 Vf?
You use the information items you're given, which for example may include time, initial velocity, initial and/or final position, or acceleration, together with the equations you've learned that express the relationship among these quantities.
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 accelleration?
Acceleration is the rate of change of velocity over time. It can be either an increase or decrease in speed, or a change in direction of motion. The formula for acceleration is given by a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
How do you find change in momentum over time given constant velocity?
To find the change in momentum over time when velocity is constant, you can use the formula Δp = m(vf - vi), where Δp is the change in momentum, m is the mass of the object, vf is the final velocity, and vi is the initial velocity. Since the velocity is constant, vf = vi, so the change in momentum will be zero over time.
How do you find acceleration if only given a velocity?
If you have an initial and final velocity and time you can figure it out with this equation, Vf squared=Vi squared1/2a(t squared) If you don't have those you cannot find acceleration. However the acceleration on Earth is a constant -9.81
What is the process for getting the formula of final velocity?
Vf= Final Velocity Vo= Original Velocity a= Acceleration t= Time Vf=Vo+a(t)
How do you find the time acquired by initial velocity in an acceleration -time graph?
To find the time taken to acquire a certain velocity in an acceleration-time graph, locate the point on the graph where the velocity reaches the desired value. Then, find the corresponding time on the horizontal axis at that point. This time value represents the time taken to acquire the initial velocity.
