How do you calculate how long it takes an object to hit the ground from a given height?

Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.

How do you calculate the flow rate of viscosity?

There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.

How do you calculate the speed of a ball before it hits the ground?

Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s . Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m .

How do you calculate viscous force?

1. The viscous force can be calculated by multiplying the shear stress acting on the surface by the fluid and the area.
2. The shear stress caused due to the viscosity of the fluid is directy proportional to the coefficient of viscosity of the fluid and the velocity gradient.

How do you calculate seconds in physics?

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

What is the velocity of the ball dropped from rest?

Ball dropped from rest If the ball is dropped from rest then that means that its initial velocity is zero, v0= 0 Then its present velocity = a •t, where a is the acceleration of gravity g ≈10 m/s2or 32 ft/s2, for example:

What is the time after the ball leaves your hand?

The solution that makes physical sense is the positive time, or 1.5 s after the ball leaves your hand.

What is the formula for a ball thrown vertically upward?

List of formulas related to a ball thrown vertically upward [formula set] 1) Maximum height reached = H = V 02 / (2 g) 2) Velocity at the highest point = 0 3) Time for upward movement = V 0 /g 4) Time for downward movement = V 0 /g 5) Total time of travel in air = (2 V 0 )/g 6) Acceleration of the

How do you find the final speed of a ball?

Two spheres of same mass will have different speeds if one is hollow and the other solid. As other answers point out, the final speed of the ball is solved by equating potential energy of the ball with its kinetic energy at the bottom of the slope.
