How do you find the initial velocity?

Answer 1

In kinemetics, i learnt that as long as you have three unknowns, you can solve the problem. If you know the distance, d; time, t; and final velocity, vf; you can figure out vi.

average velocity = total distance / total time

so d/t = (vi+vf)/2

2d/t = vi + vf

(2d/t) - vf = vi

hope this helped .good luck

Remember that this only works if the acceleration is constant.

Answer 2

To find the initial velocity of an object, you can use the equation: velocity = initial velocity + acceleration * time. If you know the acceleration, final velocity, and time, you can rearrange the equation to solve for initial velocity. Alternatively, if the object starts from rest, the initial velocity would be zero.

Answer 3

In general case, that cannot be calculated - the velocity during movement is unknown according to data.

It might be calculated only for simple cases, like for example constant acceleration during movement.

If we're considering constant - but unknown - acceleration during movement:

Distance traveled will be:

S = vstartt + at2 / 2,

and final velocity:

vfinal = vstart + at

Substituting second equation into first, we get:

S = (vfinal - at)t + at2 / 2, which is

S = vfinalt - at2/2.

Let's solve for a:

a = 2 * (vfinal / t - S / t2).

Given acceleration, we can calculate vstart:

vstart = vfinal - at

Answer 4

initial velocity is the speed or the velocity at which vechicle or any other objects starts moving.....

Answer 5

This can't be done with just final velocity and time. You need to know the acceleration. If you do know the acceleration, multiply it by the time, and subtract that from the final velocity.

Answer 6

The equation is simple Vi=vf-at
