How do you find the total time that on object is in the air with an initial velocity?

You can use the equation v = u + at from kinematics
v = final velocity, which in this case is 0 because the object eventually hits the floor.
u = initial velocity which is given to you
a = acceleration which is always 9.8m/s^2 when dealing with falling objects
t = time. manouver the equation and solve for time.
Keep in mind that I havn't taken into account movement in the x-y direction and assumed that it is just a falling object falling in the -y direction.

How do you find final Velocity of an object?
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
How do you find the initial velocity given only the distance and the time traveled?
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.
How do you find initial acceleration.?
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.
What is the formula for calculating final velocity when you know the initial speed and the acceleration?
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.
How do you find acceleration falling object with only speed and distance?
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
How do you find final Velocity of an object?
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
Which information is needed to find the time a projectile is in motion?
The object's initial distance above the ground The object's initial velocity
How do you find the initial velocity given only the distance and the time traveled?
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.
. ok v velocity a acceleration but what about you?
if by 'you', you mean 'u' then u is the initial velocity v is the final velocity. you need to know the initial velocity in trajectory question (motion of an object through the air) to find height, acceleration, time etc.
How do you find initial velocity to a moving object Simple Answers?
There are not any answers to the velocity test online. People looking for the answers will need to review the course textbooks.
How do you find initial acceleration.?
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.
What equation would you use to find the acceleration of an object of known mass if you also know the initial velocity final velocity and time over which the acceleration occured?
Use the equation a=(v-u)/t, whereby v stands for final velocity, u for initial velocity and t for time.

How do you find acceleration falling object with only speed and distance?
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
How do you find displacement when you only have acceleration initial velocity and final velocity?
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
When calculating acceleration to find the change in velocity do you subtract the initial velocity from the final velocity?
Yes.
To find acceleration you subtract what?
To find acceleration you subtract initial velocity from final velocity and divide it by time.
