If you are referring to initial velocity with vi, then
Vfinal = Vinitial + a*t, where a is a constant acceleration, and t is the time.
So you must know a t and Vfinal to find Vinitial
To find displacement using acceleration and time, you can use the formula: displacement 0.5 acceleration time2. This formula calculates the distance an object has traveled based on its acceleration and the time it has been accelerating.
To find acceleration using velocity and time, you can use the formula: acceleration (final velocity - initial velocity) / time. This formula calculates the change in velocity over a specific time period to determine the acceleration.
To find speed using acceleration and time, you can use the formula: speed acceleration x time. Simply multiply the acceleration by the time to calculate the speed.
To find velocity using acceleration and time, you can use the formula: velocity acceleration x time. Simply multiply the acceleration by the time to calculate the velocity.
To calculate velocity using acceleration and time, you can use the formula: velocity acceleration x time. Simply multiply the acceleration by the time to find the velocity.
To find acceleration using velocity and time, you can use the formula: acceleration (final velocity - initial velocity) / time. Simply subtract the initial velocity from the final velocity and divide by the time taken to find the acceleration.
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Given the initial velocity (A), final velocity (B), and time (8 seconds), you can substitute the values into the formula to find the acceleration.
To calculate the mass of the rock, you would need to know the acceleration due to gravity acting on it. Using the formula Force = mass * acceleration, you can rearrange it to find mass. Without the value of acceleration, we cannot determine the mass.
You can find the final speed by using the formula: final speed = initial velocity + (acceleration * time). Plug in the given values for initial velocity, acceleration, and time into the formula to calculate the final speed.

Acceleration can be found by dividing the change in velocity by the time it took to change. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Alternatively, acceleration can be found by using the equation acceleration = force / mass, according to Newton's second law of motion.
To find the minimum deceleration, you would need to calculate the change in velocity and time over which the deceleration occurs. Then, you can use the formula a = Δv / t, where a is the acceleration, Δv is the change in velocity, and t is the time. The minimum deceleration would be the smallest value calculated using this formula.
