Terminal velocity of a falling object can be calculated using the formula: ( v = \sqrt{\frac{2mg}{C\rho A}} ), where ( v ) is the terminal velocity, ( m ) is the mass of the object, ( g ) is the acceleration due to gravity, ( C ) is the drag coefficient of the object, ( \rho ) is the density of air, and ( A ) is the cross-sectional area of the object.

When is terminal velocity reacted by a falling object?
Terminal velocity is reached when the force of air resistance acting on a falling object equals the force of gravity pulling it downward. At this point, the object no longer accelerates and falls at a constant speed.
How do you find the velocity of a falling object?
To find the velocity of a falling object, you can use the formula v = gt, where v is the final velocity, g is the acceleration due to gravity (9.81 m/s^2 on Earth), and t is the time the object has been falling. Alternatively, you can use the formula v = sqrt(2gh), where h is the height from which the object was dropped.
Do Two objects of different masses freely fall with same momentum?
No, the momentum of an object is determined by both its mass and velocity. Since the objects have different masses, they will have different momentums even if they are falling freely.
Find the velocity in meters per second of a baseball thrown 38 m from third base to first base in 1.7 s?
If you divide the distance 38 m by the time of travel 1.7 s, then the velocity of the baseball is 22.35 m/s toward first base.
Does air resistance decrease as you move faster?
No, air resistance actually increases as you move faster. This is because the faster an object moves through the air, the more air particles it collides with per unit time, leading to a higher force of air resistance.

Terminal velocity is reached when the force of air resistance acting on a falling object equals the force of gravity pulling it downward. At this point, the object no longer accelerates and falls at a constant speed.
How do you find final velocity given height and mass?
the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5

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 the kinetic energy of a falling nickel?
The kinetic energy of a falling nickel can be calculated using the formula KE = 1/2 * m * v^2, where m represents the mass of the nickel and v is its velocity. By knowing these values, you can plug them into the equation to determine the kinetic energy.
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. CG
To find acceleration you subtract what?
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.
What is the terminal velocity of a falling cricket ball and how high would it need to be hit in order to reach that velocity?
The terminal velocity of a falling cricket ball is approximately 90-95 km/h (55-60 mph). In order to reach this velocity, the ball would need to be hit to a height of around 150-200 meters (500-650 feet) depending on various factors like air resistance and wind conditions.
How do you find the resulting velocity?
When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.
