Answer: Mass of the ball is . 42 kg. The density of air is 1.2 kg/m3.
Beside the above, what is the mass of a football? A regulation football is 28–30 cm (11–12 in) long and 58–62 cm (23–24 in) in circumference at its widest point. It weighs 410–460 g (14–16 oz) and is inflated to 65.7–68.8 kPa (9.5–10.0 psi).
Considering this, what is the volume of a football? We can compare this with the volume of a football (soccer ball) – which has a radius of around 10.5cm, therefore a volume of around 4800 cubic centimeters.
Moreover, how do you find the density of a ball?
- Formula. D = m / (4/3*pi*r^3)
- Mass.
- Radius.
Likewise, how dense is a ping pong ball? A ping-pong ball has an average density of 0.0840 g/cm3 and a diameter of 3.80 cm.
What is the mass of a deflated football in grams?
A deflated football has a smaller mass because it has fewer gas molecules inside of it. Assuming that the temperature is 32 degrees Fahrenheit (0 degrees Celsius), the mass of the air in a football inflated to 12.5 psi is about 0.39 ounces (11 g). A football deflated to only 10 psi has a mass of 0.36 ounces (10.2 g).
What is the volume of the inflated football?
We’ll assume that the footballs were inflated at a temperature of 68 degrees Fahrenheit, which is consistent with the interior thermostat setting recommended by the U.S. Department of Energy for optimal personal comfort and low energy consumption in the winter, the gametime temperature of 51 degrees Fahrenheit, the …
Does a helium filled football go further?
Helium-filled footballs will not travel further or hang in the air longer than the heavier air-filled footballs.
What is the average mass of a football player?
The average weight on an NFL player is 245.86 pounds with a bound of 2.556 pounds on the error of estimation. In conclusion the average size of an NFL player is about 6’2” 245 lbs. This is a solid goal for any kid trying to make it to the NFL. and weight of other positions.
What is the volume of a soccer ball?
The volume of the soccer ball is approximately 5,572 cubic centimeters. 11 = r The radius is about 11 centimeters.
What is the formula of volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is the volume of this cylinder?
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .
How do you find density?
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
Is volume the same as density?
Volume – How much space an object or substance takes up. … Density – How much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). The amount of mass per unit of volume.
How do you find the density of a metal ball?
What is the density of ice?
Ice has a density of 0.917 g/cm³ at 0 °C, whereas water has a density of 0.9998 g/cm³ at the same temperature. Liquid water is most dense, essentially 1.00 g/cm³, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the temperature drops to 0 °C.
What is the density of honey?
The density of honey typically ranges between 1.38 and 1.45 kg/l at 20 °C.
Are football balls heavy?
FIFA rules state that a size 5 ball must weigh between 420g (14 oz) and 450g (16 oz). … Size 4 is for use by players from 8 to 12 years old and should weigh between 350g (12 oz) and 390g (just under 14oz). Size 3 is for players under the age of 8. In this case, the required weight is set at 310g (11oz) – 340g (12oz).
Is a flat ball heavier?
An underinflated basketball or football weighs just slightly less than a properly inflated ball because its skin hasn’t changed and the weight of the air it contains is so insignificant. But the decrease in outward forces on the skin of the ball significantly changes its feel and bounciness.
Why is a deflated football better?
In the end, the reason for deflating a football owes more to physiology than physics. A slightly deflated ball is a bit softer, making it easier to grip the ball to throw it and reducing the bounce when it hits the hands of a receiver, making it easier to catch.
What is the density of the baseball g cm3?
The acceptable density range of official baseballs is between 0.70 g/cm3 and 0.80 g/cm3.
What is the concept of density without using the formula?
Density describes how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). In maths and physics, density is calculated as mass defined as mass divided by volume (Density = Mass ÷ Volume).
Do NFL footballs have chips?
Even on replay, it can be difficult. But in 2017, the league inserted a coin-sized microchip into its footballs. The chips unlocked a bottomless vault of data, and an ability to track the ball’s location. Initially, they weren’t used to aid referees.
What is AK ball in NFL?
K-balls are footballs used by the NFL for kicking plays. Shipped in directly from the Wilson factory, these balls are generally considered to be slicker and harder than the average football. They are kept separated from the rest of the balls, and a special ball boy watches over them.
