**The terminal velocity of a falling object is the same speed as the wind needed to support the weight of the object. Meaning that a falling terminal velocity of an object can be measured by placing the object in a vertical wind tunnel and measuring the airspeed needed to support the object’s weight. According to some research, the terminal velocity of a golf ball is about 32 m/s. **In this article, we are going to talk about how to calculate terminal velocity, the max speed of terminal velocity, how to find the terminal velocity of a falling object, the terminal velocity of a 200-pound man.

**The Table Below Contains Some Questions And Answers That Will Help You Get More Familiar With The Terminal Velocity Of An Object.**

How Long Does It Take A Ball To Reach Terminal Velocity? | To get to 90% of terminal velocity, it will take 8 seconds. However, you will definitely reach a much higher speed than terminal velocity if you’re falling from outer space. |

What Is The Max Speed Of Terminal Velocity? | The terminal velocity is about 120 mph (200 km/h) in a stable belly-to-earth position. There’s a terminal speed of 240-290 km/h from a stable freefall head down position. |

What Is The Terminal Velocity Of A 200-Pound Man? | The terminal velocity of a falling 200-pound man is approximately 145 mph (64.8 m/sec) according to some extensive research. |

**How To Calculate Terminal Velocity**

To calculate a terminal velocity of an object, you need to make use of the terminal velocity formula, which is; v = the square root of (2*m*g)/(p*A*C). To solve for V, which is terminal velocity, put the following values into the formula.

1. A = the object’s projected area. This means the area of the object if you projected it onto a plane that was perpendicular to the direction the object is moving.

2. m = mass of the falling object.

3. ρ = the density of the fluid the object is falling through.

4. C = the coefficient of the drag. The shape of the object determines the number. The coefficient of an object is normally to lower the more streamlined it is in the shape. You can look up some approximate drag coefficients

5. g = the acceleration due to gravity. It is appropriately 9.8 meters per second on earth.

Then, find the mass of the falling object. The mass of an object is normally measured in kilograms or grams, in the metric system.

Since pounds is a measuring unit of force and not really of mass, you need to take note while using the imperial system. The pound-mass (IBM) is the unit of mass in the imperial system, which will definitely experience a force of 32 pound-force (Ibf) under gravitational force on the surface of the earth. Let’s take, for instance, a person actually weighs 160 Ibf with a mass of 5 Ibm even if the person originally weighs 170 pounds on earth.

After finding the mass of the falling object, you need to know the acceleration due to the gravity of the earth. The acceleration due to the gravity of the earth is 9.8 meters per seconds squared, or 32 feet per second squared.

Then, try to calculate the downward pull of gravity. The mass of the object multiplied by the acceleration due to gravity is equal to the falling force of the object after being pulled down, or F = MA. This number, multiplied by two, moves at the top of the formula for terminal velocity.

**How Long Does It Take A Ball To Reach Terminal Velocity?**

To get to 90% of terminal velocity, it will take 8 seconds. However, you will definitely reach a much higher speed than terminal velocity if you’re falling from outer space. Interestingly, you will slow down as you reach the atmosphere. You might just burn up like a meteorite if you’re coming in from a far distance.

**What Is The Max Speed Of Terminal Velocity?**

The terminal velocity is about 120 mph (200 km/h) in a stable belly-to-earth position. There’s a terminal speed of 240-290 km/h from a stable freefall head down position. To speed of around 500 km/h (310 mph), is, however, accomplished through a further minimization of drag by streamlining the body.

**How Do You Find The Terminal Velocity Of A Falling Object?**

In a layman’s language, the square root of the quotient of twice the object’s total weight all-over the object’s frontal area product, the gas density of the medium, and its drag coefficient is equal to the terminal velocity of the object.

**What Is The Terminal Velocity Of A 200 Pound Man?**

The terminal velocity of a falling 200-pound man is approximately 145 mph (64.8 m/sec) according to some extensive research.

Falling Object | Mass | Area | Terminal Velocity | |

Skydiver | 75 kg | 0.7 m^{2} | 60 m/s | 134 mi/hr |

Baseball (3.66cm radius) | 145 gm | 42 cm^{2} | 33 m/s | 74 mi/hr |

Golf ball (2.1 cm radius) | 46 gm | 14 cm^{2} | 32 m/s | 72 mi/hr |

Hail stone (0.5 cm radius) | 0.48 gm | 0.79 cm^{2} | 14 m/s | 31 mi/hr |

Raindrop (0.2 cm radius) | 0.034 gm | 0.13 cm^{2} | 9 m/s | 20 mi/hr |

However, if we make use of a drag coefficient of C = 0.5 gives and assume the hailstones to be spherical, it gives the following:

Radius (cm) v (km/hr) v(m/s) v(mi/hr) .01 7 1.9 4.3 0.1 22 6.1 13.7 0.2 31 8.6 19.3 0.5 49 13.6 30.5 1.0 69.5 19.3 43.2 2.0 98.3 27.3 61 3.0 120 33.4 74.8 5.0 155 43.2 96.6 10.0 220 61 136 |

**Closing Thoughts**

The bottom line is that the terminal velocity of a falling object is the identical velocity as the wind required to help support the mass of the item. As outlined by some research, the terminal velocity of any golf ball is approximately thirty-two meters per second. We’ve come to the closing chapter of this informative article.
