Momentum = (mass) times (velocity) = 0.25 x 40 = 10 kg-m/sec
Their difference is that a 15 gram ball is lighter than a 60 gram ball.
2.7 gram, 40 mm diameter. (introduced after the 2000 Olympic Games)earlier it was 38 mm. (40 mm table tennis ball is slower and spins less than a 38 mm one).Stars on the ball indicate the quality of the ball. 3 stars indicates that it is of the highest quality, and is used in official competitions.
The official rules of table tennis state that the ball shall:weigh 2.7g andbe spherical, with a diameter of 40mm andbe made of celluloid or similar plastics material andbe white or orange, and matt
Sure. That's a perfectly good unit of momentum. So is (any unit of mass) divided by (any unit of speed).
use the Impulse-Momentum theorem where (Fnewtons)(tseconds)=change in momentum change in momentum=Pf-Pi; P=mv
I'm having trouble seeing the list from here. (Any unit of mass) divided by (any unit of volume) is a unit of density. Widely used units include: -- gram/cubic centimeter -- gram/milliliter -- kilogram/cubic meter -- poundmass/cubic foot
The older 38 mm table tennis balls as of the year 2000 were officially substituted by 40 mm balls. This is now the standard. The international rules specify that the game is played with a light 2.7 gram, 40 mm diameter ball. At the same time, 2.67 to 2.77 grams is deemed acceptable. In the same way diameters of 39.5 mm to 40.50 mm may be used.
15
gram
For a 38mm diameter ball (not regulation, but common):4/3*pi*r^3 = 9145.33 cu mm = 9.145 cc (cubic centimeters).1 cc water = 1 mL water = 1 gram water = 0.035274 AVDP Oz = 0.0022046 AVDP PoundSO:Your 38mm ping pong ball displaces 9.145 mL Water (or 9.145 gram Water, or 0.323 AVDP oz, or 0.02016 AVDP Pound.)It would take roughly 50 of these balls to displace one pound of water.
That's impossible to answer. A teaspoon is a measurement of volume. Whereas a gram is a measurement of weight. A gram of feathers might be the size of a golf ball where a gram of lead might be smaller than a pencil eraser.
