## How do you find final speed with distance and time?

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

## How do you find initial speed and final speed?

If you have values for the final velocity, acceleration, and time involved, you can use the following equation:
1. Initial velocity: Vi = Vf – (a * t)
2. Understand what each symbol stands for. Vi stands for “initial velocity” …
3. Note that this equation is the standard equation used when finding initial velocity.

## How do you calculate kilometers per hour?

Speed is distance divided by time. Simply put, if you drove 60 kilometres for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h.

## How do you calculate Ke final?

Final kinetic energy KE = 1/2 m1v’12 + 1/2 m2v’22 = joules. For ordinary objects, the final kinetic energy will be less than the initial value.

## How do you find speed with force and distance?

v^2 = u^2 +2as, v=final velocity, u = intial velocity=0, a=(f/m), s is distance over which the object is accelerated.

## How do you find speed with force?

Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time. Displacement = velocity × time.

## How do you calculate speed using work energy theorem?

The work-energy theorem says that this equals the change in kinetic energy: −mg(yf−yi)=12(v2f−v2i). (yf−yi)=(sf−s−i)sinθ, so the result for the final speed is the same.
