For the same reason it's not measured in buckets of rotten fish: because those would not be the correct units.
Angular momentum is the cross product of the linear momentum and the position vector relative to the center of rotation. If you do a dimensional analysis, you'll see that the proper units are joule-seconds.

What is the angular momentum of a 0.730 kg ball rotating on the end of a thin string in a circle of radius 0.950 m at an angular speed of 14.7 rad per second?
the angular momentum is given by:.L = mass (m) * velocity (v) * radius (r)you have the mass and radius, so to calculate the velocity:.circumference = 2 * pi * r = 2 * 3.1416 * 0.95 = 5.969 metres14.7 rad / sec = 2.3396 rev / secso velocity = circumference * rev / sec = 2.3396 * 5.969 = 13.965 metres / sec.so:.L = m * v * r = 0.73 * 13.965 * 0.95 = 9.685 n-m-s
What is the unit of momentum?
Momentum is measured in kilograms per metre per second (kgms^-1)
What is momentum measured in?
Momentum is mass times velocity (MxV).Mass is in kg and velocity is in m/s.This means that the answer should read kg x m/s.This is not equivalent to newtons which is kg x m/s^2.
What is the final angular speed of the system if a solid horizontal cylinder of mass 10 Kg and radius 1m rotates with an angular speed of 7.00 rad slash s about a fixed vertical axis?
7 radians per second IS the angular speed in this case. You don't need to calculate anything else.
What is the momentum in kg-m?
Momentum is actually measured in kilograms x meters/second, since it is the product of a mass and a speed. Momentum can be thought of as the "amount of motion", and it is a physical quantity that is conserved under all circumstances, as far as we know.
What is the unit of angular momentum?
joule seconds or newton meter seconds depending on what system you use

What is the angular momentum of the 2.6 kg 5.6 cm diameter rotating disk.?
Without knowing the angular speed, i.e. RPM or some such velocity, it is not possible to answer the question. Please restate the question, giving all of the required information.

What is the unit measurement for monemtum?
Linear momentum is (mass)*(velocity)[a vector mv], so the SI unit would be kg*m/s, angular momentum is the sum of all resultant vectors of r x mv for each point on a spinning object, and would have units kg*m2/s

what is the momentum of a 1400kg car traveling at 25 m/s?
The momentum of a 1400 kg car traveling at 25 m/s is: momentum = mass x velocity momentum = 1400 kg x 25 m/s momentum = 35,000 kg m/s Therefore, the momentum of the 1400 kg car traveling at 25 m/s is 35,000 kg m/s
If a truck has a momentum of 25000 kg ms and a car has a momentum of 5000 kg ms what is the total momentum of the two truck?
i would have to say 30000 kg ms but i may be wrong
