The angular momentum of a spinning wheel decreases from 8.4 kilogram-meter squared per second to 4.7 kilogram-meter squared per second over a period of 2.1 seconds. What average torque was applied?
To find the average torque applied, we can use the formula for torque (( \tau )) in terms of angular momentum (( L )): ( \tau = \frac{\Delta L}{\Delta t} ), where ( \Delta L ) is the change in angular momentum and ( \Delta t ) is the change in time. The change in angular momentum is ( 4.7 - 8.4 = -3.7 ) kg·m²/s. Therefore, the average torque is ( \tau = \frac{-3.7 , \text{kg·m}^2/\text{s}}{2.1 , \text{s}} \approx -1.76 , \text{N·m} ).
When kinetic energy doubled what happens to momentum?
If kinetic energy is doubled, the momentum will remain the same. Kinetic energy and momentum are related, but momentum depends on mass and velocity while kinetic energy depends on mass and velocity squared. Therefore, doubling kinetic energy will not affect momentum.
What is the momentum and derive the formula for the momentum?
Momentum is the product of the mass and the velocity of an object. It's SI unit is kgms-1. Correct, but perhaps more easily interpreted as kgm/s.
If you are at rest do you have momentum?
The momentum of a body is defined as the product of is mas and velocity. Momentum = Mass x Velocity. If a body is at rest then obviously its velocity is zero. Therefore, its momentum also becomes zero.
Why is momentum M times V?
Simply because physicists discovered that it is a product that is conserved. In collisions of two objects for example, if you add up the momentum before the collision the momentum will be the same after the collision. Note that momentum is not something that has a concrete reality. A rock sitting on the ground has zero momentum relative to us here on earth but has alot of momentum relative to someone on mars. It can not have zero momentum and alot of momentum at the same time, it depends on ones frame of reference. My point is that momentum is not at 'concrete" thing. Refer to the 'Conservation of linear momentum' in Wikipedia.org, "The World's Encyclopedia" *Check out related links*
What is the fuel range for the Pontiac G6 Convertible?
"The Pontiac G6 convertible gets on average 25 miles per gallon. It could get as well as 70 mpg on highways, or as low as 15 in city driving. Overall, if you are buying a G6, gas is probably not a concern." Totally incorrect answer above. The fuel range is around 375 miles on average.
What is a g6 as in like a g6?
I don't know what you mean by - as in like a G6, but a G6 is an aeroplane or a car of some sort (:
What is the average momentum of a 70kg runner who covers 400 m in 50 s?
The average momentum of the runner can be calculated by multiplying the mass of the runner by his average velocity. To find the average velocity, we divide the distance covered by the time taken. In this case, the average momentum would be 9400 kg m/s.
What are formulas to prepare marksheet of students in excel?
=IF(AVERAGE(C6:G6) < 50,"fail","pass")
What is the average momentum of a kg runner who covers a distance of M in A seconds?
The average momentum of a runner can be calculated by dividing the mass (in kg) of the runner by the time taken to cover the distance (in seconds). This gives the average momentum of the runner during that time period.
What do they mean feeling so fly like a g6 in the song like a g6?
g6 is a jet. feelin so 'FLY' like a G6
Is a g6 a car or plane?
its a plane. like the song called G6, " Fly like a G6
What is the average momentum of a 50 Kg runner who covers 400 meter in 50 second?
The average momentum of the runner in this case can be calculated by multiplying the mass of the runner by the average velocity. The average velocity of the runner is the total distance divided by the total time taken, which in this case is 400m/50s = 8 m/s. Therefore, the average momentum is 50 kg * 8 m/s = 400 kg.m/s.
Is there a 2010 g6?
No, 2009 was the final year for the G6
What is a g6 far east movement?
A "G6" is actually a jet.
What is feeling like a G6?
Feeling like a G6 is feeling "fly". It is used in such songs as "Like a G6". A G6 is a very fast and small airplane. Kind of like a jet. That is why people use the term "I'm feeling so fly like a G6".
A 0.068-kilogram ball with a velocity of 22.1 meters per second strikes a wall. The wall stops the ball in 0.36 second. What is the average magnitude of the force applied to the ball by the wall?
To find the average force, we need to use the equation: average force = change in momentum / time. First, calculate the initial momentum of the ball: momentum = mass * velocity. Then, calculate the change in momentum by subtracting the initial momentum from 0 (since the ball stops). Finally, divide the change in momentum by the time taken for the collision to find the average force applied by the wall.
