Distance = (1/2 of acceleration) x (time squared)
You can change this around to solve it for acceleration or time.
(Time squared) = (distance)/(half of acceleration)
Time = the square root of [ (2 x distance)/(acceleration) ]
Be careful . . .
This is only true if the distance and the speed are both zero when the time begins.
If the distance and velocity are both zero when time=0, thenDistance = 1/2 (acceleration) x (time)2
To find the acceleration if the time is not given, you will need to know the velocity and the distance. Then, use this equation: d = vt + (1/2)at2 to solve the problem by plugging in your numbers for the distance and the velocity.
You can't you need the time and distance (once you have that it's just distance/time).
Measurements of acceleration are given in units of distance/time.
Assuming you start from rest (0) and accelerate uniformly. > acceleration = distance / (0.5 * time2), then having found acceleration: > final velocity = acceleration * time
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
The equation that does involve time is.. v² = v₀² + 2ad
The distance travelled by an object in a given time is given by:Distance = Speed * TimeAlternatively for an object that is accelerating:Distance = (Speed of object before acceleration is applied * Time) + (0.5 * Acceleration * Time squared)If the object is accelerating from speed zero, the first set of brackets is irrelevant.Also, if the object is falling to the ground, acceleration = 9.81
If you are only given total distance and total time you cannot. If you are given distance as a function of time, then the first derivative of distance with respect to time, ds/dt, gives the velocity. Evaluate this function at t = 0 for initial velocity. The second derivative, d2s/dt2 gives the acceleration as a function of time.
There is no information that shows any relationship with time. Since acceleration is a variable related to time, it is impossible to answer the question.
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
-- With the distance the mass moved and the time it took, all you can find is its average speed during that time. -- If you had its two different distances at two different times, then you could find an acceleration. -- With an acceleration and the mass, you can then find the force on it.
formula for speed is distance traveled over time taken to cover distance acceleration is given by change in velocity per unit time
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.
(Distance covered) and (time to cover the distance) is enough informationto calculate average speed during the time, but not enough to calculateacceleration.
Time equals velocity divided by acceleration. t=v/a
This is imposible to calculate. In order to find acceleration, knowlege of at least 3 of these variables must be given: initial speed, final speed, distance, and time.
the general form of the units for acceleration are distance per time squared, such as m/s2.
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.
a=s/t, and s=d/t, so if we substitute... a = (d/t)/t --> a = d/t2 You must know both the acceleration and time in order to solve for the distance travelled.
Acceleration is the rate of change of the function of velocity per unit time. This means that the unit of acceleration is distance per unit time squared.
The speed at the end of the time is (speed at the beginning of the time) plus (acceleration x length of time)
You use the information you're given, along with the equations and formulas you know that relate distance, time, speed, and acceleration, to calculate the number you're asked to find. And here's a tip: Chances are that the initial acceleration, the final acceleration, and the acceleration all along the way, are all the same number.
