One formula that can be used - assuming constant acceleration, of course! - is vf2 = vi2 + 2as, where vf is the final speed, vi is the initial speed, a is the acceleration and s is the distance. In your case, solve for final velocity.
Time = distance / average speed Average speed = 1/2 (initial + final)
Distance = |(v2 - u2)/(2a)| where initial velocity = u final velocity = v accelaration = s
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
If you take initial velocity(Vi) to be zero and the final velocity (Vo) to be a known. Puting the knowns into a triganonomical equation and solving for the value of D would give an answer
The formula for finding that out is velocity = distance / mass
You can only know the distance for sure if acceleration or deceleration is constant. Add the start and end velocities and divide by two and then multiply by the time to get your distance.
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
you cannot figure out the change in velocity given just the distance and loss of potential energy. you need more information
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.
since time is given you are done
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.
Velocity is distance over time, and acceleration is change in velocity over time. You can get the time by dividing deceleration by velocity (of course, taking the absolute value). From there, velocity equals distance over time. Distance is velocity * time.
D=vt+1/2(at^2)WhereD=Distancev=Initial Velocitya=Accelerationt=TimeExcept we do not know the time t. Use v2 = u2 - 2aD. u is final velocity.
By using the formula in physics
(acceleration X time) + beginning velocity = final speed
V= vi + at
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
velocity is a vector quantity. Its magnitude is given by (velocity)= (distance)/(time)
Assuming you start from rest (0) and accelerate uniformly. > acceleration = distance / (0.5 * time2), then having found acceleration: > final velocity = acceleration * time
You can't. The mass is irrelevant to velocity. You need the distance.
Use the formula Acceleration = (final velosity - initial velocity)/ time.
Velocity is in distance/time, so multiplied by 1/distance would give you 1/time. Hope this helps!
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
