acceleration times speed
You cannot. Force is mass times acceleration. You have neither.
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
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.
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.
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)
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.
The speed at the end of the time is (speed at the beginning of the time) plus (acceleration x length of time)
Time = Speed/Accleration only if acceleration is constant, and initial velocity is 0.
(acceleration X time) + beginning velocity = final speed
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
If the distance and velocity are both zero when time=0, thenDistance = 1/2 (acceleration) x (time)2
Divide the distance by the time; the quotient is speed.
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.
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.
Acceleration = Change in Speed divided by Time over which the change takes place. If acceleration is constant then Acc = [Final Speed - Initial speed] / Time If not, Acc = gradient of Speed-Time graph.
Distance = time * average speed (velocity) Average speed = Distance/time
(Distance covered) and (time to cover the distance) is enough informationto calculate average speed during the time, but not enough to calculateacceleration.
-- 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.
The answer depends on what information you are given.
There are several different equations that can be used to find acceleration. The right one to choose depends on what information is given or measured. Examples: -- You're given the mass of an object and the force acting on it. Acceleration = (force) divided by (mass) -- You're given the starting and ending speed of a car, and how much time it was moving. Average acceleration = (change in speed) divided by (time for the change) -- An object started out from rest. You're told how far it moved and how long it took. Average acceleration = (2 x distance) divided by (time squared)
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 you need the time and distance (once you have that it's just distance/time).
Speed = Time x acceleration
speed equals to acceleration into time
