You can't. All you can tell from time and distance is
the average speed during that time.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
a = (v2 - u2)/2s where a is the acceleration between the initial point in time and the final point in time, u is the initial velocity v is the final velocity s is the distance travelled
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.
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.
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
To find the distance traveled by an object with a given acceleration and initial velocity, you can use the formula: distance (initial velocity time) (0.5 acceleration time2). This formula takes into account the initial velocity, acceleration, and time the object has been moving to calculate the total distance traveled.
To find the acceleration of an object, you can use the formula: acceleration change in velocity / time taken. If you have the distance and time measurements, you can calculate the velocity by dividing the distance by the time. Then, you can find the change in velocity by subtracting the initial velocity from the final velocity. Finally, divide the change in velocity by the time taken to find the acceleration.
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
The object's initial distance above the ground The object's initial velocity
You can use the equation: distance = (initial velocity + final velocity) / 2 * time. This formula assumes constant acceleration.
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
The equation that relates the distance traveled by a constantly accelerating object to its initial velocity, final velocity, and time is the equation of motion: [ \text{distance} = \frac{1}{2} \times (\text{initial velocity} + \text{final velocity}) \times \text{time} ] This equation assumes constant acceleration.
To find acceleration, you subtract the initial velocity from the final velocity and then divide by the time taken to achieve the change in velocity. The formula for acceleration is (final velocity - initial velocity) / time.
In the kinematic equations for distance, the relationship between initial velocity, acceleration, and time is that the distance traveled is determined by the initial velocity, the acceleration, and the time taken to travel that distance. The equations show how these factors interact to calculate the distance an object moves.
