Average speed = 1/2 (initial speed + final speed)
Time = (distance)/(average speed)
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
You use the information you're given, along with the equations and formulas you know that express some kind of relationship between the information you're given and the initial and final velocity.
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
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.
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.
The formula for calculating acceleration is: acceleration (final velocity - initial velocity) / time elapsed.
You can find the distance using the equation: distance = (final velocity)^2 / (2 * acceleration). Square the final velocity, divide it by twice the acceleration to get the distance traveled before coming to a stop.
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.
You cannot.
To find the initial velocity of the box when it fell out, you can use the formula: final velocity squared = initial velocity squared + 2 * acceleration * distance. Given that the final velocity is 0 m/s, acceleration is 3 m/s^2, and distance is 24 meters, you can solve for the initial velocity.
To find the final velocity when given the acceleration and time, you can use the formula: final velocity initial velocity (acceleration x time). Simply plug in the values for acceleration and time, and calculate the final velocity.
