(vf-vi)/ t is ?
A equals Vf minus Vi divided by time equals triangle v divided by time
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time
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.
acceleration cannot be calculated from these values alone unless one makes a few assumptions: Vf=final velocity Vi=initial velocity a=acceleration d=displacement t=time assume Vi=0 (Vf-Vi)/t=a Vf=at+Vi Vf**2=Vi**2+2ad (at)**2=2ad aatt=2ad att=2d a=2d/t**2
(vf-vi)/ t is ?
A equals Vf minus Vi divided by time equals triangle v divided by time
A=Vf-Vi/t Acceleration is the final velocity minus the initial velocity divided by the time it too to reach it
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time
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.
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
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.
Vavg = (Vi + Vf)/2 Vi = 0 Vavg = Vf/2 Vf = 2*Vavg Vavg = 80 Vf = 160
Work is done when a force is applied to move an object over a distance. So, work leads to motion, as the application of force causes a change in the position of an object. The work done on an object is directly related to the distance over which the force is applied and the magnitude of the force.
acceleration cannot be calculated from these values alone unless one makes a few assumptions: Vf=final velocity Vi=initial velocity a=acceleration d=displacement t=time assume Vi=0 (Vf-Vi)/t=a Vf=at+Vi Vf**2=Vi**2+2ad (at)**2=2ad aatt=2ad att=2d a=2d/t**2
